Hydrogen Production from Semiconductor-based Photocatalysis via Water Splitting
Hydrogen is the ideal fuel for the future because it is clean, energy efficient, and abundant in nature. While various technologies can be used to generate hydrogen, only some of them can be considered environmentally friendly. Recently, solar hydrogen generated via photocatalytic water splitting has attracted tremendous attention and has been extensively studied because of its great potential ...
متن کاملSolar Hydrogen Production via a Samarium Oxide-Based Thermochemical Water Splitting Cycle
The computational thermodynamic analysis of a samarium oxide-based two-step solar thermochemical water splitting cycle is reported. The analysis is performed using HSC chemistry software and databases. The first (solar-based) step drives the thermal reduction of Sm2O3 into Sm and O2. The second (non-solar) step corresponds to the production of H2 via a water splitting reaction and the oxidation...
متن کاملNanoscale Effects in Water Splitting Photocatalysis.
From a conceptual standpoint, the water photoelectrolysis reaction is the simplest way to convert solar energy into fuel. It is widely believed that nanostructured photocatalysts can improve the efficiency of the process and lower the costs. Indeed, nanostructured light absorbers have several advantages over traditional materials. This includes shorter charge transport pathways and larger redox...
متن کاملHydrogen producing water treatment through solar photocatalysis†
Hydrogen is being intensively investigated as a new energy carrier that stores and transports energy obtained from renewable energy resources (e.g., solar and wind power) to the point of use. In particular, efficient methods that can convert solar energy into hydrogen are being actively sought. One of the ideal methods is solar hydrogen production from water splitting that can be driven by phot...
متن کاملAnalysis of Solar Thermochemical Water-Splitting Cycles for Hydrogen Production
Approach • Review all published papers, reports, patents, etc. in the past 25+ years that relate to thermochemical water-splitting cycles, in general, and solar driven cycles, in particular. • Use FactSageTM program to perform chemical equilibrium calculations. • Employ HYSYS/ASPEN Plus chemical process simulation (CPS) program for developing process flowsheet, process analyses and optimization...
