Abstract

Inside Back Cover: The present work in doi:10.1002/idm2.12169 demonstrates a scaffoldcorrelated evolved gas bubble behavior in the gas production electrocatalysis by threedimensional printing nickel-based sulfide (3DPNS) electrodes with varying scaffold structures. The primary objective was to explore the correlation between the number of hole sides (HS) present in the electrode scaffolds and the release of gas bubbles. In the context of the alkaline hydrogen evolution reaction (HER), an increase in the number of HS was observed to lead to a faster overflow of H2 bubbles, and this acceleration was attributed to the reduced size of the overflowing bubbles. The research outcomes hold significance in advancing the design and development of catalytic electrodes.
