One-pot synthesis of PtIn/3D-GNs composites with high alloying degree for electro-photo synergistic catalysis

Abstract

Alloyed PtIn/3D-GNs composites exhibit efficient electro-photo-catalysis under irradiation, deriving from the synergy between the charge separation of In2O3 and SPR excitation of In(0).

Synergistic photo-enhanced electrocatalysis of Pt–ZnO–Bi2O3 heterojunction for methanol oxidation under visible light illumination

“…This further reveals that the combination of Bi 2 O 3 and ZnO to Pt is beneficial for excellent stability and tolerance of CO, owing to the synergistic effects for both electrocatalytic and photo-electrocatalytic properties. 92,93…”

“…This further reveals that the combination of Bi 2 O 3 and ZnO to Pt is beneficial for excellent stability and tolerance of CO, owing to the synergistic effects for both electrocatalytic and photo-electrocatalytic properties. 92,93 To understand the surface poisoning effect and evaluate the CO tolerance of the synthesized binary and ternary catalysts, a CO oxidation experiment was performed under dark and light conditions.

“…This reveals that ZnO-Bi 2 O 3 support accelerates the oxidative removal of CO from the Pt surface and offeres an abundant hydroxyl source for the oxidation of CO and released active sites of Pt for further CO or methanol oxidation by visible light illumination. 25,[92][93][94] Pt-ZnO (PZ) has a lower peak potential compared to PtXC72 in both dark and light, indicating the higher anti-poisoning ability of PZ. 13 The ECSA was calculated from CO stripping experiments (Fig.…”
