“…The BET surface area, pore size, and pore volume of the materials are given in Table 1. 42 As can be seen, the introduction of FEMO in g-C 3 N 4 enhances the surface area of composite FEM-10, indicating its higher catalytic activity. Furthermore, both pristine g-C 3 N 4 and FEM-10 show hierarchical mesoporosity, which is one of the major factors in showing higher CO 2 absorption properties.…”

In this study, simplex centroid mixture design was employed to determine the effect of urea on ZnO-CeO. The heterojunction materials were synthesized using a solid-state combustion method, and the physicochemical properties were evaluated using X-ray diffraction, nitrogen adsorption/desorption, and UV–Vis spectroscopy. Photocatalytic activity was determined by a triclosan degradation reaction under UV irradiation. According to the results, the crystal size of zinc oxide decreases in the presence of urea, whereas a reverse effect was observed for cerium oxide. A similar trend was observed for ternary samples, i.e., the higher the proportion of urea, the larger the crystallite cerium size. In brief, urea facilitated the co-existence of crystallites of CeO and ZnO. On the other hand, UV spectra indicate that urea shifts the absorption edge to a longer wavelength. Studies of the photocatalytic activity of TCS degradation show that the increase in the proportion of urea favorably influenced the percentage of mineralization.

“…212,213 More charge carriers were produced for water splitting because of increased optical absorption upon doping Zn. 214,215 The increase in the absorption intensity upon Znmodification indicated a strong interaction between Zn and the matrix of g-C 3 N 4 which arose from the d−p repulsion between 3d and 2p orbitals of Zn and N, respectively. 211 In a study of Ding et al, 216 they also reported a simple treatment under high temperature (at 600 °C) to obtain alkali metal (including K, Li, or Na)-doped g-C 3 N 4 .…”

Hydrogen energy is environmental-friendly and considered an attractive alternative to fossil fuels. Among the feasible technologies for hydrogen generation, photocatalysis-derived hydrogen from water splitting is considered to be the optimal solution for meeting long-term sustainability and increased energy demands. In this context, various photocatalytic genres are proposed, with metal and carbon-supported photocatalysts demonstrating greater comprehensiveness and potential for addressing solar-driven hydrogen production from water. Several important aspects of the aforementioned photocatalytic genres are reviewed in the present work in an effort to provide pertinent researchers with new horizons for more advanced performance. The review is initiated by introducing the primary principles in photocatalysis, as well as the prerequisites for hydrogen generation from water. The focus then moves to metal-based photocatalysts, where the important features of these materials as photocatalysts are summarized. Related limitations are also discussed, along with the proposed strategies that could potentially mitigate them. Similar systematic summaries are made of knowledge on carbon-based photocatalysts. The review concludes with a discussion of potential future research directions in light of the bottlenecks currently encountered. With the proper research and development, metal-based and carbon-based photocatalysts could produce clean hydrogen from water, thereby fueling global development without causing environmental harm.
