The pursuit of sustainable and renewable energy has directed researchers to explore microalgae and black soldier flies as potential sources for biodiesel production. This study focused on the commercial viability of co-culturing these two organisms for biodiesel, highlighting their symbiotic relationship. Microalgae harness sunlight through photosynthesis to produce chemical energy, while black soldier flies contribute essential nutrients and biomass. This synergy aids in carbon dioxide fixation and sustainable biodiesel production. Through optimized culture conditions and extraction processes, the researchers achieved impressive lipid yields and conversion rates, rendering biodiesel production economically feasible. This paper examines the energy implications and scalability of this novel biodiesel production system, suggesting that co-culturing microalgae and black soldier flies presents a promising approach to overcoming energy constraints. This innovative technology holds significant potential for advancing sustainable energy solutions and meeting global energy demands.

Laminarization nano sheets perovskite catalytic performance in water treatment and energy review is rare. The self-assembly materials showed super surface， nano sheet layers as well as small crystalline, self-assembly nano sheets are powder samples which means it can be facially recycled after photo catalytic reaction as well as stored at normal conditions, but pristine nano sheets must be stored in alkaline solution as well as will undergo aggregation. In review, auxiliary, the co-doping, computational simulation, self assembly, nano sheets have a better prospect. Different preparation methods of perovskite are compared, the research progress of perovskite modification is described. Perovskite catalysts also have some shortcomings, such as: the mechanism of catalytic degradation needs to be further explored. Utilizing compound preparation methods, finding better doping materials as well as exploring the appropriate structure as well as loading carrier, utilizing biblio metric method to be the hot spots of perovskite materials in photo catalytic research. In recent years, the research trend of perovskite materials has gradually changed from simple ion doping to complex doping, as well as then to load.
