Alkaline modified A-site deficient perovskite catalyst surface with exsolved nanoparticles and functionality in biomass valorisation

Environmental problems associated with the use of fossil fuels and increase in energy demands due to rise population rapid industrialisation, are driving forces for energy. Catalytic conversion biomass renewable energies is among promising approaches materialize above. This requires development robust catalysts suppress deactivation carbon deposition agglomeration. In this work, surface properties chemistry such as exsolution B-site metal catalyst nanoparticles, particle size distribution, well catalyst-support interactions were tailored through alkaline dopants enhance catalytic behaviour valorisation glycerol. The incorporation metals into lattice an A-site deficient perovskite modified basic morphology a consequent interaction. resulted materials where hydrogen selectivity over 30% CO 60% observed. ability reduce fouling result during operation was also profound interaction occurring at exsolved nanoparticles their socketing synergy between dopant alloy systems. particular, one designed systems, La0.4Sr0.2Ca0.3Ni0.1Ti0.9O3±δ, displayed almost 100% resistance deposition. Therefore, rearrangement using choice suitable could be improve performance.
