A Novel Example of Molecular Hydrogen Generation from Formic Acid at Visible-Light-Responsive Photocatalyst

Abstract

Scanning electron microscope observationThe structural characterization of Cu 2 O was conducted using a scanning electron microscope (SEM, Hitachi S-800) equipped with an energy dispersive X-ray fluorescence spectrometer (Kevex, Quantum Dry).

Visible-light-driven hydrogen production from water in a noble-metal-free system catalyzed by zinc porphyrin sensitized MoS 2 /ZnO

“…The 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin ligand and M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 6 ZnO nanoparticles were purchased from Aldrich. ZnTCPP dye was synthesized according to a recent report [44].…”

“…Various semiconductors, such as metal oxides, sulfides, oxynitrides, and organic polymers, have been specially designed to develop highly efficient and stable photocatalytic hydrogen production systems [5][6][7][8][9][10]. Among various metal oxide semiconductor photocatalysts, nanostructured zinc oxide has been proven to be a suitable candidate for solar-to-H 2 conversion owing to its low-cost, nontoxicity, excellent stability and abundance [11,12].…”

Achievements and Trends in Photoelectrocatalysis: from Environmental to Energy Applications

“…Nowadays, photoelectrocatalysis is a technique with consolidated principles that has gained prominence and has been successfully applied in organic compound oxidation [4][5][6], inorganic ion reduction [7,8], microorganism inactivation [9,10], CO 2 reduction [11,12], and production of electricity and hydrogen [13][14][15][16]. The subject has since been explored by several researchers and reviews of deserving notoriety [13,[17][18][19][20].…”

Fate of methanol under one-pot artificial photosynthesis condition with metal-loaded TiO2 as photocatalysts

“…(7) is the unprecedented photocatalytic generation of H 2 from formic acid [77]. Even with H 2 as the carrier gas, the reacted amount of formic acid was similar and almost all the reacted formic acid converted to CO 2 .…”

“…More interestingly, when our reaction was carried out in the liquid phase, the TOF increased to 14,950 h −1 . Most importantly, the catalyst does not undergo deactivation and does not produce carbon monoxide even after a continuous usage for a week, unlike heterogeneous thermocatalysts [77,78].…”
