Undoubtedly, photocatalysis, as an emerging technology capable of rapidly removing pollutants or facilitating \"green\" energy conversion, has become a promising strategy for addressing these challenges.The burgeoning domain of two-dimensional (2D) monoelemental materials, commonly referred to as Xenes, has attracted significant interest within the field of photocatalysis due to their graphene-like 2D architecture and unique properties. These novel 2D monoelemental materials encompass a diverse array of elements spanning from group IIIB to VIA in the periodic table, including borophene, silicene, and phosphorene. Nevertheless, the rapid recombination of photogenerated electrons and holes, coupled with inherent defects in certain 2D Xenes, continue to impede their practical applications. To address these challenges, the utilization of heterostructures based on 2D Xenes has garnered widespread attention and been widely employed as an enhanced strategy. By strategically pairing different semiconductors, Xenes-based heterostructures (composed of the Xene and other nanomaterials) can ingeniously integrate the functions of different materials while manipulating their internal transfer of carriers to suppress electron-hole recombination. Herein, a review of the research progress on 2D Xenes and their heterostructures in the field of energy and environmental application. Specifically, the different charge transfer mechanisms of heterostructures based on 2D monoelemental materials are compared, and the related applications of photocatalysis are discussed.

This paper conducts simulation and experiments on the particle exhaust performance of three types of cryopanels under tokamak application conditions. The simulation results indicate that the cryopanels composed solely of metal plates exhibit superior surface cooling performance compared to the cryopanels coated with granular activated carbon (GAC), and the latter's surface cooling performance is affected by the adhesive types and contact condition between the GAC and the adhesive. Subsequently, the manufacturing processes of different cryopanels were developed and their prototypes were produced, and a testing platform was established to test their performance. The experimental results indicate that the cryopanel without GAC coating exhibit high pumping speeds for deuterium and hydrogen at low temperature, but they are highly sensitive to temperature fluctuations. Above 8 K for deuterium and 5.5 K for hydrogen, this cryopanel becomes ineffective in pumping these gases. Conversely, cryopanels coated with GAC exhibit less temperature sensitivity in pumping deuterium and hydrogen, with minimal changes in pumping speeds observed between 4.5 K and 20 K. Within the experimental temperature range, cryopanel without GAC coating exhibits no pumping ability on helium, whereas those with GAC coating possess helium pumping capability.
