Abstract
Alcohol electrooxidation reaction (AOR) is of sluggish kinetics, which as the anodic reaction of direct alcohol fuel cells determines largely the discharging performance of the device. Solar energy as an endless energy source is introduced to promote the AOR kinetics. Herein, the recent progress on photo‐promoted AOR and the application in fuel cells is reviewed, including 1) design of the AOR photoelectrocatalysts, 2) photoelectrocatalysis mechanism, and 3) fabrication of photo‐promoted direct alcohol fuel cells (PDAFCs). Finally, a perspective on the challenges of PDAFCs and new directions in this exciting and still emerging research area are given.
