Challenges and opportunities:•Photocatalytic overall water splitting is an intriguing process to produce hydrogen. However, the photocatalytic efficiency unsatisfactory. Thus, it necessary analyze challenges for splitting.•The unfavorable thermodynamics, sluggish kinetics, dissolved oxygen, backward reaction, side reaction make enormously difficult. These obstacles must be overcome achieve in s...

In this paper we analyze the convergence of the splitting method for shallow water equations. In particular we give an analytical estimation of the time step which is necessary for the convergence and then we study the behaviour of the motion of the shallow water in the Venice lagoon by using the splitting method with a finite element space discretization. The numerical calculations show that t...

Dye sensitized solar cells (DSSCs) use low-cost materials, feature tunable molecular sensitizers, and exhibit quantum efficiencies near unity. These advantageous features can be exploited in the context of solar water splitting by functionalizing DSSCs with catalysts for water oxidation and reduction. This article will cover the development of photoanodes for water splitting DSSCs from the pers...

Researchers are intensively investigating photochemical water splitting as a means of converting solar to chemical energy in the form of fuels. Hydrogen is a key solar fuel because it can be used directly in combustion engines or fuel cells, or combined catalytically with CO(2) to make carbon containing fuels. Different approaches to solar water splitting include semiconductor particles as phot...
