Surface deposition of Ba II on Pd/H y WO 3− x nanowires was developed by using a solution‐phase atomic layer deposition process. The procedure involves the generation of Brønsted surface OH sites by H 2 spillover on Pd/WO 3 , which can then hydrolytically condense with Ba(OEt) 2 to produce surface Ba II . At just 0.2 at % Ba, CO production by the light‐assisted activity of the reverse water–gas shift (RWGS) reaction was observed to increase by about 300 %. In situ DRIFTS studies suggested enhanced CO 2 capturing capabilities of a Ba‐decorated surface. This study further exemplifies the importance of surface chemistry in optimizing materials for catalysis.
