The (0 0 2) exposing facets of WO3 boosting photocatalytic degradation of nitrobenzene

Construction of yolk‐shell structural polydopamine@WO3 micro/nanospheres for enhanced photocatalytic degradation

“…[8] Tungsten oxide (WO 3 ) is an n-type of semiconductor like TiO 2 , [9] ZnO [10] and other metal oxides. [11] Resulting from wide light absorption, [12] low band gap (2.3-2.8 ev), [13] better mechanical property and stability, [14] low cost and non-toxicity, [15] it has been concerned in catalysis and optoelectronic fields including photocatalysis, [16] energy storage [17] and gas sensitivity. [18] However, the low conduction band edge (∼ 0.8 eV vs NHE (Normal Hydrogen Electrode)), rapid carrier recombination, [19] low electron transport capacity and limited light response range [20,21] of WO 3 make its photocatalytic ability be hindered.…”
