1. A method for preparing doped tin oxide material, comprising:
preparing a precursor solution, wherein the precursor solution consists of water, or wherein the precursor solution comprises core-shell particles, wherein the core-shell particles are core-shell nanoparticles or core-shell microparticles;
heating the precursor solution to at least 60° C.;
adding a sodium stannate solution to the precursor solution to form a mixture comprising tin oxide material;
preparing a doping solution, wherein the doping solution comprises an antimonate salt or a zinc salt;
adding a specific amount of the doping solution to the mixture comprising tin oxide material to form a reaction mixture;
heating the reaction mixture to at least 150° C. for a period of time; and
collecting doped tin oxide material from the reaction mixture, wherein the doped tin oxide material comprises stand-alone tin oxide particles or tin oxide core-shell particles, and wherein the doped tin oxide material further comprises antimony or zinc.
