The Use of Composite TiO2/Activated Carbon Fibers as a Photocatalyst in a Sequential Adsorption/Photocatalysis Process for the Elimination of CiprofloxacinAbstract This work reports the performance of a sequential adsorption/photocatalysis process using activated carbon fibers with deposited TiO2 for the elimination of the antibiotic ciprofloxacin (CIP) in water. A commercial activated carbon fiber (ACF10) was selected as the support, and a TiO2 coating was synthesized using Metal Organic Chemical Vapor Deposition (MOCVD). Experiments were carried out using a photocatalytic reactor irradiated with monochromatic [...] |

Abstract Fuel cells based on renewable synthetic fuels are promising alternatives to fossil fuel combustion for efficient electricity production. Much focus has been placed on hydrogen as a chemical fuel, but being a flammable gas, there are challenges with its safe handling. Formic acid is an attractive liquid fuel for use in direct formic acid or formate fuel cells, and it can in principle be produced from the thermal or electrochemical reduction of carbon dioxide. Over the past ten years, [...] |
Determining the Band Alignment at the BiVO4|NiOOH Interface Using the Hybrid DFT TechniqueAbstract It is important to understand the band offsets between semiconductors, which are crucial to determine the direction of electron transfer at the interfaces. Two methods are normally used to determine the direction from the first principles: alternating slabs put in contact (without empty spaces between them) and separate calculations for each material surface in the presence of vacuum spaces. The first method may introduce distortions due to insufficient epitaxial match, which may lea [...] |
One-Pot Tandem Synthesis of Nitriles and Amides from Biomass Platform CompoundsAbstract In recent years, research on converting biomass platform compounds into high-value chemicals and pharmaceutical intermediates has garnered huge interest. Nitrile and amide groups are key structures in natural products and biologically active molecules. The direct conversion of biomass platform compounds into nitriles and amides will undoubtedly be an important guide for biomass utilization. In this paper, a facile and efficient triphosgene-assisted one-pot conversion for aldehydes an [...] |
Controllable Cyclopalladated Polythiophene Imine Monolayer by Self-Assembly, Hybrid Doping and Electrochemical Polymerization: A Simple Way to Enhance Activity and StabilityAbstract In this article, an approach to generate self-assembly cyclopalladated polythiophene imine monolayers (denoted as ITO@Pd-CPTIMs) is described. The monolayers were fabricated by combining self-assembly (SA), hybrid doping (HD), and electrochemical polymerization (ECP) called SA-HD-ECP. The catalytic activity and stability of the polymerized monolayers in the Suzuki coupling reaction were improved by modulating the struct [...] |
Acetonitrile Combustion over Copper-Based Nanocatalysts: A Structure-Performance Relationship StudyAbstract In this paper, the relationship between activity and structure of Cu2+ in different chemical environments of Cu-BETA, La2CuO4, and CuO nanocatalysts was systematically investigated for acetonitrile combustion. The study revealed that exchanged and octahedral species of Cu2+ coexist in Cu-BETA, while octahedral species are dominant in CuO and La2CuO4

Abstract Regardless of their size, supported gold nanoparticles are largely used for liquid-phase oxidation reactions. Small gold nanoparticles exhibit good performance during the reduction of organic compounds. The direct reduction of carboxylic acid to aldehyde is a famous and familiar reaction in the field of organic chemistry and is considered as one of the fundamental chemical transformations. Herein, we present Au/hydrotalcite, Au/MgO, and Au/Al2O3 [...] |
