However, the low photogenerated charge separation efficiency and the lack of effective active sites seriously constrain the reaction efficiencies of semiconductor photocatalysts for N<sub>2</sub> reduction of ammonia synthesis. Therefore, the rational design of catalytic materials is the key to enhance the photocatalytic N<sub>2</sub> reduction reaction of ammonia synthesis. Transition metal Ru as the active center not only accelerates the adsorption and activation of N<sub>2</sub> molecules, but also has good selectivity for N<sub>2</sub> reduction. Moreover, the interaction between the metal and the support can effectively regulate the electronic structure of the active site, accelerate the photogenerated electron transfer, and significantly enhance the photocatalytic activity. Based on this, this review systematically investigates the Ru co-semiconductors to realize efficient photocatalytic N<sub>2</sub> reduction for ammonia synthesis, and introduces its basic principles. Specifically, the Ru co-semiconductor photocatalytic material systems are introduced, such as TiO<sub>2</sub>-based, g-C<sub>3</sub>N<sub>4</sub>-based, and metal oxide materials, including the design of catalysts, crystal structures, and other characteristics.

Optimizing the structural characteristics of the PTL is important for enhancing the overall performance of PEMWE. In this study, a three-dimensional steady-state PEMWE model is firstly developed. Based on the model, polarization curves of the PEMWE under different PTL parameters are computed, and the impacts of three characteristic parameters, i.e. porosity, thickness, and conductivity, on the PEMWE performance are thoroughly investigated. Then, the corresponding performance optimization strategies are proposed by incorporating a multilayer perceptron (MLP) machine learning model. It shows that porosity plays a dominant role in the PTL performance among the three parameters, followed by thickness, with conductivity having a relatively minor impact. The increasing of porosity and reducing of thickness can effectively enhance the electrolyzer performance.
