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 structure and morphology in hybrid doping using different thiophene derivatives, concentrations, and sc [...]

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. All nanocatalysts achieved high conversion rates of acetonitrile, which rapidly increased with temperature. CuO and La2CuO4 led to the formation of undesired products [...]

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 systems as heterogeneous versatile catalysts to realize the oxidation [...]

The objective of this research was to analyze the effect of different concentrations of nitric and hydrochloric acids on the structural, acidic, and catalytic properties of a post-synthetic treated ZSM-5 type zeolite at various temperatures. The properties of zeolite catalysts were determined using different methods, such as the Brunauer-Emmett-Teller (BET) method for specific surface area, temperature-programmed desorption (TPD) of ammonia method for acidic properties, and a flow-through unit with fixed bed cataly [...]

Fe-rich alloys have been widely studied as catalyst materials for the cathodic oxygen reduction reaction (ORR) in hydrogen fuel cells, and many have shown high activities. The stability of Fe-rich catalysts has also been researched, and some studies have shown promising results using an accelerated stress test (AST), which uses a potential cycling method. However, for commercial fuel cell applications, such as standby power systems, the catalyst has to tolerate a high potential for a long period, which can not be r [...]

The photocatalytic reaction involved in TiO2 photocatalysis was investigated using a microreactor coated with TiO2 film on the glass plate attached on one side of the microreactor. It was confirmed that the effect of H2O2 on the photocatalytic degradation efficiency of azo dyes (acid orange 7, acid red 151, and acid yellow 23) was dependent on the polymorphs (anatase and rutile) of TiO2 coated on the glass plate of the UV-irradiated microreactor. Scavengers of holes (KI) and electrons (p-benzoquinone) were added to [...]

One-pot synthesis of mesoporous hybrid material consisting of Mn-Co/CoO nanoparticles encapsulated in an N-doped graphene shell decorated with Mo2C nanoparticles (Mo2C-NC@Mn-Co/CoO) was reported. The Mn and Mo components synergistically refined the graphitized carbons due to the interactions with N and C atoms while promoting the stability of the Co/CoO nanoparticles. These components exhibited a beneficial effect on the dispersion of the active metal/metal oxide nanoparticles and the formation of a mesoporous stru [...]

Wastewater from stamped batik (batik cap) — the block-printing method that dominates micro, small, and medium enterprise (MSME) production across Southeast Asia — is commonly discharged without a transferable design basis for continuous-flow scale. This study links batch-scale electrocoagulation-filtration (EC-F) kinetics to operational current-density projections for a 1 m3/day wastewater treatment plant, complemented by techno-economic and carbon footprint assessments. A 2 × 3 factorial batch experiment with alum [...]

This study aims to determine the physical and mechanical properties of boards developed at the Centro Experimental de la Vivienda Económica (CEVE, Experimental Center for Economic Housing) from unshredded Tetrabrik waste. The boards were produced via thermo-compaction, using the polyethylene from the outer layers of Tetrabrik containers as a binder. Their intended application is as wall panels for social housing. The performance of these new boards was compared with that of conventional market-available boards of s [...]

This study explored how organisations in Zimbabwe integrate climate risk into Environmental Management Accounting (EMA) and how this enhances sustainable value creation. The study adopted the Institutional Theory and the sensemaking lens. It employed an inductive, interpretivist, qualitative research design, utilising in-depth interviews with 11 senior professionals in accounting, operations, non-governmental organisations (NGOs), sustainability, and regulatory positions. Climate risk awareness was found to be prim [...]
