In September 2020, Yun-Jung Chung's Paper "Coupling Effect of Piezo-Flexocatalytic Hydrogen Evolution With Hybrid 1T- and 2H-Phase Few-Layered MoSe2 Nanosheets", has been published on Adv. Energy Mater. 2020, 10, 2002082
Hybrid 1T‐and 2H‐phase MoSe2 nanosheets with active reaction sites, which display strong piezoelectric responses and extraordinary flexoelectric potential (flexopotential), are demonstrated. The piezo‐ and flexopotential coupling effect is observed on polarized surfaces of the MoSe2 nanosheets across the top and bottom surfaces, thus establishing an internal electric field to separate electron–hole pairs and proceeding with electrochemical reaction with polar molecules, generating hydrogen gas at ≈5000 µmol g−1 h−1.

In July 2020, Yu-Ting Lin's paper "Simultaneous Piezoelectrocatalytic Hydrogen-Evolution and Degradation of Water Pollutants by Quartz Microrods@Few-layered MoS2 Hierarchical Heterostructures" has been published on Advanced Materials 32, 34 (2020) 2002875
This study develops a novel piezoelectrocatalysis system, which involves quartz microrods (MRs) abundantly decorated with active‐edge‐site MoS2 nanosheets to form a quartz microrods@few‐layered MoS2 hierarchical heterostructure (QMSH). An efficient piezoelectrocatalytic hydrogen evolution reaction and decomposition of wastewater without light irradiation can be achieved simultaneously. The piezoelectrocatalytic process may be a promising method for treating industrial wastewater and producing clean energy.

Nov. 2019, Yu-chun Wang's paper "Effect of Controlled Oxygen Vacancy on H2-Production through the Piezocatalysis and Piezophototronics of Ferroelectric R3C ZnSnO3 Nanowires" has been published on Advanced Functional Materials 30 (2020) 1907945
This study is the first to demonstrate that ferroelectric R3c LiNbO3‐type ZnSnO3 nanowires (NWs), through the piezocatalysis and piezophototronic process, demonstrate a highly efficient hydrogen evolution reaction (HER) with H2‐production rate of approximately 3453.1 µmol g−1 h−1and approximately 6000 µmol g−1 in 7 h.
