Special Issue Information

Dear Colleagues,

Clean and carbon-free hydrogen exhibits promise regarding its capacity to become the most feasible energy carrier of traditional fossil fuels. Photocatalytic technology could convert sustainable solar energy to hydrogen without the emission of any contaminants; therefore, addressing energy issues and achieving carbon neutrality is an appealing approach. This specific field has already attracted extensive attention and is now relevant in the domain of solar-to-hydrogen efficiency, fulfilling the requirements of industrial application.

This Special Issue, entitled “New Advances in Photocatalytic Hydrogen Production”, will cover the most recent progress in the discovery of novel materials and the design of efficient catalysts, the fundamental exploration of the reaction mechanism, and the development of advanced characterization methods, etc., relating to photocatalytic hydrogen production. This Special Issue welcomes the submission of original research and review papers within its scope and aims to inspire further developments in this expanding and prospering research field.

Compound parabolic concentrator (CPC) photocatalytic reactors are commonly used for photocatalytic water splitting in hydrogen production. This study aimed to gain a better understanding of the physical processes in CPC photocatalytic reactors and provide theoretical support for their design, optimization, and operation. The analysis involved the ray tracing approach, Euler–Euler two-fluid model, and discrete ordinates method (DOM) to study solar radiation transfer and particle flow in the reactor. The distribution of solar radiation on the receiving tube’s surface after CPC concentration was obtained by conducting the ray tracing approach. This solar radiation distribution was then coupled into the Euler–Euler two-fluid model to solve for the natural convection flow field, the temperature field, and particle phase volume fraction distribution inside the receiving tube over a period of 120 s. Lastly, the discrete ordinates method (DOM) was used to analyze the transfer of radiation inside the receiving tube at different times, obtaining the distribution of local volume radiative power absorption (LVRPA) and the total radiative power absorption (TRPA) inside the tube. The results showed that the TRPA reached its maximum at 120 s, accounting for 66.61% of the incident solar UV radiation. According to the above results, it could be suggested that adopting an intermittent operation mode in CPC photocatalytic reactors is reasonable and efficient. Full article
