Epitaxial p-type SiC as a self-driven photocathode for water splitting

Nickel Coated Silicon Photocathode for Water Splitting in Alkaline Electrolytes

Cu2O Photocathode for Low Bias Photoelectrochemical Water Splitting Enabled by NiFe-Layered Double Hydroxide Co-Catalyst

Layered double hydroxides (LDHs) are bimetallic hydroxides that currently attract considerable attention as co-catalysts in photoelectrochemical (PEC) systems in view of water splitting under solar light. A wide spectrum of LDHs can be easily prepared on demand by tuning their chemical composition and structural morphology. We describe here the electrochemical growth of NiFe-LDH overlayers on C...

A silicon-based photocathode for water reduction with an epitaxial SrTiO₃ protection layer and a nanostructured catalyst

The rapidly increasing global demand for energy combined with the environmental impact of fossil fuels has spurred the search for alternative sources of clean energy. One promising approach is to convert solar energy into hydrogen fuel using photoelectrochemical cells. However, the semiconducting photoelectrodes used in these cells typically have low efficiencies and/or stabilities. Here we sho...

Recent Progress in Energy‐Driven Water Splitting

Hydrogen is readily obtained from renewable and non-renewable resources via water splitting by using thermal, electrical, photonic and biochemical energy. The major hydrogen production is generated from thermal energy through steam reforming/gasification of fossil fuel. As the commonly used non-renewable resources will be depleted in the long run, there is great demand to utilize renewable ener...

A hybrid energy cell for self-powered water splitting†

We fabricated a hybrid energy cell that consists of a triboelectric nanogenerator, a thermoelectric cell, and a solar cell, which can be used to simultaneously or individually harvest the mechanical, thermal, and solar energies. Instead of using an external power source, the hybrid energy cell can be directly used for self-powered water splitting to generate hydrogen. The volume of the produced...
