报告摘要：
Residual agro-industrial biomass poses environmental and health risks when released into natural environments, but it can also serve as a feedstock for value-added products. We introduce bioactive additives (phyto-catalysts) into digestion systems to regulate biochemical processes, achieving a 2–2.5-fold increase in biogas production rate along with higher methane content during anaerobic digestion. Experimental results are supported by theoretical calculations that clarify the catalytic mechanisms. In parallel, the presentation investigates TiO2 (anatase)-based photocatalysts. Cation doping broadens light absorption, enhances radical redox activity, and suppresses electron–hole recombination, thereby improving quantum efficiency. A chemical-catalytic method for metal deposition on TiO2 nanoparticles is demonstrated as an effective strategy for designing efficient photocatalysts. The developed processes enable the production of composite materials with tailored properties, enhancing the photocatalytic degradation of organic pollutants in water.
