Abstract In many research fields, researchers are often stuck with problems that are difficult to overcome for decades altough tremedous effort has been devoted. Finding high-performance catalysts and photoelectrochemical (PEC) electordes for water splitting and CO2 reduction is the one of great examples. We might be able to find solutions from unconventional routes. In this talk, I will introduce some examples of uncenventional approaches that can potentially provide solutions in sluggished research fileds. First, enhanced water oxidation can be achieved by inducing spontaneous dipoles in PEC electrodes compared to those without dipoles. Second, well-designed nanopatterned array structures can drastically improve the selectivity of electrochemical conversion of water and CO2. Lastly, simple surface chemical functionalization can change triboelectric property of a polymer substrates and can enhance power output of nanogenerators compared to conventional engineering methods.
