Excessive consumption of fossil fuels gives rise to the increasing emission carbon dioxide (CO 2 ) in atmosphere and furthers ecocrisis. Electrochemical CO reduction (ECR) has both functions dwindling greenhouse gas concentration converting it into valuable products. Due intrinsic chemical inertness molecules, study on efficient low‐cost catalysts attracted much attention. Recently isolated atoms, dispersed stable support, play an important role decreasing energy barriers intermediate steps...
Tetrafluoromethane (CF4), as a typical perfluorocarbon (PFC), has remarkable global warming potential (GWP) of 7390 and an ultralong lifetime 50 000 years, making its effective treatment crucial for mitigating environmental impact. Catalytic hydrolysis is promising way decomposition, in which Al-based materials have been widely used efficient catalysts. However, the deficiency strong Lewis acidic-tricoordinated Al (AlIII) sites strongly limits their catalytic performance. In this work, CF4...

Abstract Opposition-based differential evolution (ODE) is a well-known DE variant that employs opposition-based learning (OBL) to accelerate the convergence speed. However, existing OBL variants are population-based, which causes many shortcomings. The value of jumping rate not self-adaptively adjusted, so algorithm easily traps into local optima. population-based wastes fitness evaluations when converges sub-optimal. In this paper, we proposed novel called subpopulation-based (SPOBL) with...
