Activated Carbon Catalysis And Loaded Catalyst

Graphitized carbon and amorphous carbon are components of the crystal form of activated carbon, exhibiting functions similar to crystal defects due to their unsaturated bonds. Activated carbon is widely used as a catalyst due to the presence of crystal defects, and its large specific surface area and porous structure also make it widely used as a catalyst carrier.
The surface chemical properties of commercial activated carbon can be altered by γ radiation treatment without affecting its physical properties. The role of surface chemistry in photocatalysis was studied through ultraviolet radiation and simulated solar radiation, showing that activated carbon can play a photocatalytic role in both types of radiation.
By measuring hydroxyl radicals and superoxide anion radicals in UV/activated carbon and simulated solar/activated carbon systems, it was demonstrated that using activated carbon as a photocatalyst and photo-induced reactant can effectively eliminate the influence of impurities on the reaction. The acquisition of hydroxyl radicals and superoxide anion radicals in the system is much higher than using light radiation alone, providing new possibilities for free radical chemistry development and new reactions.
Due to its complex composition, activated sludge has a slow anaerobic degradation process. Some scholars have utilized granular activated carbon for anaerobic treatment processes with promising results.
decomposition of activated sludge, which has increased methane production by 17.4% during the process of activated sludge decomposition and also increased activated sludge decomposition rate by 6.1%. In addition, the introduction of - SO3H on the surface of activated carbon has a catalytic effect on the synthesis of methyl tert amyl ether. This catalyst is easy to prepare, has high catalytic activity, and is not easy to decompose, demonstrating the enormous potential of modified activated carbon catalysts. Research has shown that using granular activated carbon supported ozone system can achieve a catalytic oxidation rate of 48.1% for humic acid, providing a new pathway for the degradation of humic acid. The study on the electrocatalytic oxidation of phenol using activated carbon loaded alumina as a modified activated carbon paste electrode showed good stability and reusability, while having a relatively low detection limit and a wide detection range.
