Abstract Piezocatalysis is an emerging technique that holds great promise for the conversion of ubiquitous mechanical energy into electrochemical energy through piezoelectric effect. However, mechanical energies in natural environment (such as wind energy, water flow energy, and noise) are typically tiny, scattered, and featured with low frequency and low power. Therefore, a high response to these tiny mechanical energies is critical to achieving high piezocatalytic performance. In comparison to nanoparticles or 1D piezoelectric materials, 2D piezoelectric materials possess characteristics suc...

Semiconductor photoelectricity (PE)/photoelectrochemistry (PEC) as an ideal technology is expected to overcome challenges in renewable energy conversion and environmental remediation. However, fast recombination of photo-generated charges severely restricts PE/PEC conversion efficiency. Furthermore, the static electric field is prone to be saturated by free carries, resulting in decay of photoelectric/photochemical conversion efficiency. To overcome above-mentioned problems, the construction of permanent internal electric field is an effective strategy to improve photo-electricity or -chemistr...
