Biofuel production, hydrogen production and water remediation by photocatalysis, biocatalysis and electrocatalysis

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(3), P. 1315 - 1379

Published: March 10, 2023

Abstract The energy crisis and environmental pollution have recently fostered research on efficient methods such as catalysis to produce biofuel clean water. Environmental refers green catalysts used breakdown pollutants or chemicals without generating undesirable by-products. For example, derived from waste inexpensive materials are promising for the circular economy. Here we review photocatalysis, biocatalysis, electrocatalysis, with focus catalyst synthesis, structure, applications. Common include biomass-derived materials, metal–organic frameworks, non-noble metals nanoparticles, nanocomposites enzymes. Structure characterization is done by Brunauer–Emmett–Teller isotherm, thermogravimetry, X-ray diffraction photoelectron spectroscopy. We found that water can be degraded an efficiency ranging 71.7 100%, notably heterogeneous Fenton catalysis. Photocatalysis produced dihydrogen (H 2 ) generation rate higher than 100 μmol h −1 . Dihydrogen yields ranged 27 88% methane cracking. Biodiesel production reached 48.6 99%.

Enhancement of Fixed-bed Flow Reactions under Microwave Irradiation by Local Heating at the Vicinal Contact Points of Catalyst Particles

Scientific Reports, Journal Year: 2019, Volume and Issue: 9(1)

Published: Jan. 14, 2019

The formation of local high temperature regions, or so-called "hot spots", in heterogeneous reaction systems has been suggested as a critical factor the enhancement chemical reactions using microwave heating. In this paper, we report generation regions between catalyst particles under First, demonstrated that rate dehydrogenation 2-propanol over magnetite was enhanced 17- (250 °C) to 38- (200 fold when heated with irradiation rather than an electrical furnace. Subsequently, existence microwave-generated specific heating coupled simulation electromagnetic fields and heat transfer well situ emission spectroscopy. Specific high-temperature were generated at vicinal contact points due concentrated electric field. We also directly observed during model silicon carbide spherical material conclude is key for enhancing fixed-bed flow irradiation.
