▎ 摘　　要

NOVELTY - Preparation of nanocellulose whisker molybdenum disulfide/graphene-based composite counter electrode material comprises preparing molybdenum disulfide nanorods by using cellulose whiskers as template and graphene oxide and carbonizing at high temperature under nitrogen atmosphere. The composite counter electrode material has hollow structure with porosity of 0.10-0.80 cm3/g. The mass ratio of molybdenum disulfide nanorods, graphene and amorphous carbon is 1:0.001-0.06:0.2-0.6. USE - Method for preparing nanocellulose whisker molybdenum disulfide/graphene-based composite counter electrode material used for dye-sensitized solar cell (claimed). ADVANTAGE - The product has hollow nano-structure and large specific surface area which is beneficial to the permeation of electrolyte and the transmission of electrons, and provides more catalytic active sites for redox reaction in electrolysis. The method is simple, low-cost and environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of nanocellulose whisker molybdenum disulfide/graphene-based composite counter electrode material comprising adhering nanocellulose whisker-based molybdenum disulfide/graphene composite counter electrode material to conductive glass substrate by using ethyl cellulose solution containing acetylene black to obtain counter electrode used in dye-sensitized solar cell where concentration of ethyl cellulose solution is 2-15% and acetylene black content is 5-20%.
