- Abstract
In this article, a 3D photocatalytic support with different Poisson's ratio was used for the first time to control the photocatalytic production rate of hydrogen. It was created by a stereo-lithography method, and the support with the most negative Poisson's ratio got the best result. The Poisson's ratio of the 3D structure influences the rate of hydrogen production, and it is important for the photocatalyst supports to be porous for light to penetrate into them. A series of Ce doped CdS photocatalysts were produced and immobilized on 3D multicellular Al
2 O3 supports. By changing the proportion of Ce3+ doped into the CdS photocatalysts 1 % of Ce3+ exhibited optimal hydrogen production, which was 222.9 % compared to that of the pure CdS. Using the 3D photocatalytic support with different Poisson's ratio, the photocatalytic production rate of hydrogen increased by 128 %., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Inc.
