In recent years, researchers have been actively investigating metal oxide-based materials with narrow bandgaps due to their potential applications toward wastewater treatment and oxygen evolution reactions (OER). this study, we successfully synthesized g-C3N4 (GCN), Fe2O3, Fe2O3/g-C3N4 (FGCN) using thermal polymerization hydrothermal methods. We characterized the physicochemical structural properties of these through various analytical techniques including XRD, FT-IR, UV-DRS, XPS, FE-SEM, HR-TEM analyses, confirming effective construction FGCN composite catalyst. evaluated photocatalytic activity GCN, catalysts by assessing ability degrade rhodamine B (RhB) crystal violet (CV) exposing them sunlight for 150 min. Among catalysts, demonstrated excellent performance, achieving 93 % 95 degradation RhB CV, respectively, under min exposure. The developed Fe2O3/g-C3N4@Nickel foam (FGCN@NF) catalyst exhibits remarkable OER a reduced Tafel slope 64 mV/dec low overpotential 290 mV at current density 10 mA/cm2 shows durable performance over long time (15 h). Total Organic Carbon (TOC) analysis confirmed mineralization both dyes. remained largely unchanged after five consecutive experiments, demonstrating reusability photostability. Trapping experiments revealed that O2●– is main species responsible decomposition dyes Therefore, development versatile photo/electrocatalytic system can efficiently promote energy conversion in environmental has attracted great attention.

Graphitic carbon nitride (g-C3N4) has been proven as a potential photocatalyst in the research arena of water remediation, energy harvesting and organic dye degradation etc. Even though, g-C3N4 profound properties viz. photochemical stability, intriguing electronic band structures, suitable light harvesting, bandgap 2.7 eV even it significant drawbacks such poor disparity, low surface area high recombination rate photogenerated electron-hole pairs that leads to reduced photocatalytic activity. However, these could be overcome by compositing with sulfides, ferrites other metal oxides which provides charge separation, increased better absorption. This detailed review focuses on various synthesis methods g-C3N4-based secondary/ternary nanocomposite applications hydrogen evolution, pollutant degradation, oxygen evolution CO2 photoreduction. Alongside, this critical also summarizes recent literature deals preparation g-C3N4/polymer composites their storage environmental remediation applications.

In this work, an efficient bimetallic catalyst was developed to serve as a key factor for the successful hydrogenation of biomass-derived furfural (FF) high-value-added chemicals, namely 2-methylfuran (2- MF) and furfuryl alcohol (FA). The bare SBA-16 (SB-16) Rux/Niy/SBA-16 (RuxNiySB-16) catalysts with different weight percentages (x = 0.2, 0.4, 0.6, 0.8, 0.9 wt% y 0.1 wt%) were prepared through in situ hydrothermal method. Characterization using XRD, FT-IR, FE-SEM, EDS, XPS, Pyridine HR-TEM analysis confirmed chemical physical properties catalyst. To investigate catalytic FF 2-MF 2-propanol (2-PrOH) over RuxNiySB-16 catalysts, various reaction parameters such temperature, time, loading, ratio have been carried out. Among tested, Ru0.8Ni0.2SB-16 demonstrated outstanding performance under mild conditions, achieving 100% conversion impressive selectivity 88% towards 2-MF. high can be attributed combined influence metal acid sites on surface.
