Description

A kind of flower-shaped carbon load MoS2Composite of nano particle and preparation method thereof
Technical field
The invention belongs to catalysis material technical field, and in particular to a kind of liberation of hydrogen catalysis material and preparation method thereof and should With.
Background technology
In world's today, the population of rapid growth and industry are to the bigger demand of the energy and the environmental crisis for thus causing The more effective more environmentally friendly energy of exploitation is set to become more and more urgent.Wherein Hydrogen Energy as a kind of most potential energy, due to height Combustion heat value and reusable edible the characteristics of be considered as being likely to replace fossil energy in future.At present, electrochemistry hydrogen manufacturing is still It is so a kind of method for preparing hydrogen being widely used.In order to improve the efficiency of electrochemistry hydrogen manufacturing, generally requiring to use can be with Reduce the catalyst of overpotential of hydrogen evolution, the catalyst of platinum base is considered as most effective of which catalyst, because its liberation of hydrogen mistake Current potential is no better than zero.But platinum is few in earth content, and expensive, so as to greatly limit them in business Large-scale application.Therefore, the base metal liberation of hydrogen catalyst for developing low cost, high efficiency and high stability just becomes very must Will.To current, existing various non-platinum based catalysts are proved to catalytic activity for hydrogen evolution high, such as《Germany should change》 (Angew. Chem. 2015, 127, 1)The iron of report is nanocrystalline,《JACS》(J. Am. Chem. Soc. 2013, 135, 17881)The molybdenum bisuphide of report,《Germany should change》(Angew. Chem. Int. Ed. 2014, 53, 12855)The phosphatization cobalt of report and and《Energy and environment science》(Energy Environ. Sci., 2013, 6, 943) Molybdenum carbide of report etc..
Molybdenum bisuphide(MoS2)It is a kind of typical two-dimensional layer material, liberation of hydrogen catalysis material is prepared based on it and is received Extensive concern is arrived.In the past few years, substantial amounts of theoretical and experimental study discloses the catalytic activity of hydrogen evolution of molybdenum bisuphide Mostly come from the unsaturated sulphur atom positioned at edge.But its intrinsic low conductivity and serious agglomeration traits are inhibited The conduction of electronics and catalysis activity edge it is exposed, cause poor catalytic activity of hydrogen evolution.It is substantial amounts of to grind in order to solve these problems Study carefully and be devoted to nano level MoS2It is supported on electrically-conductive backing plate to form molybdenum bisuphide-carbon hybrid material, such as Graphene, carbon Nanotube and some other carbon material.Such as, Dai Hongjie etc. exists《JACS》(J. Am. Chem. Soc. 2011,133,7296) report MoS at first2Nano particle in situ is grown on graphene film preparing liberation of hydrogen catalysis high The composite of activity.Then, by MoS2Nano particle is supported on《Application material and interface》(ACS Appl. Mater. Interfaces, 2014, 6 (23), 21534)The graphene aerogel of report,《Advanced function material》(Adv. Funct. Mater. 2013, 23, 5326)The mesoporous grapheme foam of report,《Nanoscale》(Nanoscale, 2013, 5, 7768; Nanoscale, 2014, 6, 5624)The CNT and graphene paper of report and《Materials chemistry will A》(J. Mater. Chem. A, 2015,3, 5041)Carbon fiber foam of report etc. prepares the work quilt of liberation of hydrogen catalytic composite materials Report in succession.These work show the material electronicses conducting power for improving and increase exposed MoS2Active number of edges is shadow Ring two key factors of catalysis activity.
Although the Graphene and CNT of various structures are often used to load MoS2Nano particle, but these conductive bases The preparation process of body is often relatively costly, and environmental pollution is larger.And biomass are just wide due to its source and recyclability It is used for preparing conductive carbon material generally.Hydrothermal carbonization method is a kind of extensive adopted method of conversion of biomass, because this It is method low cost, environment-friendly and easily operated.The biomass enough to hydrothermal carbonization further carry out high-temperature heat treatment can be with Significantly improve the electric conductivity of material.Additionally, studies have reported that during the hydrothermal carbonization of biomass, adding some template materials Material, such as graphene oxide sheet or MoS2Piece, can make the hydro-thermal carbon coating of generation on these mould material surfaces.
In the present invention, we realize the hydro-thermal carbon coating of biomass on flower-shaped ZnO surfaces by hydro-thermal method first, through subsequent High temperature cabonization and acid etch after, obtained flower-shaped carbon material.Then with conductive flower-shaped carbon it is again substrate and tetrathio molybdenum Sour ammonium solvent heat finally gives MoS2Nano particle is supported on the nano composite material on flower-shaped carbon.As liberation of hydrogen catalysis material, Flower-shaped carbon can not only provide material good electronic conduction ability, additionally due to it and MoS2Between strong interaction may be used also Significantly to suppress MoS2Reunion so that exposed more active MoS2Edge.In addition flower-shaped carbon three-dimensional porous knot in itself Structure, can also increase the contact area with electrolyte, and promote hydrionic diffusion.Therefore this material shows relatively low analysis Hydrogen take-off potential, less Tafel slope and good long-time stability.
