A one-pot hydrothermal strategy was used to synthesize Pt/GNs (PAMAM) & Pt/GNs (CS) composites. Pt nanoparticles are deposited onto graphene sheets (GNs) via synchronous reduction of K₂PtCl₄ and graphene oxide (GO) under hydrothermal conditons wi...

Supported copper oxide nanoparticles are a potential candidate for replacing the rare and expensive precious metals within the automotive three-way catalyst. However, a well-designed dispersion method is necessary to allow a stable high loading of ac...

It is highly desirable to design functionalized supports in heterogeneous catalysis regarding the stabilization of active sites. Pd immobilization in porous polymers and henceforth its application is a rapidly growing field. In virtue of its’ scalabl...

In this study, the optical properties of a TiO₂ photocatalyst were enhanced with various impregnations of Er³⁺ and Ni²⁺ separately, using the impregnation method as photocatalysts for the direct solar photolysis degradation of chloroxylenol. The synt...

Due to the continuously rising demand for C₃–C₅ olefins it is important to improve the performance of catalysts for dehydrogenation of light alkanes. In this work the effect of modification by SiO₂ on the properties of the alumina support and the chr...

Low temperature fuel cells (LTFCs) are considered as clean energy conversion systems and expected to help address our society energy and environmental problems. Up-to-date, oxygen reduction reaction (ORR) is one of the main hindering factors for the...

To contribute to the search for an oxygen-free biodiesel from vegetable oil, a process based in the oleic acid hydrodeoxygenation over Ni/γ-Al₂O₃ catalysts was performed. In this work different wt % of Ni nanoparticles were prepared by wetness impreg...

In this comprehensive review, the main aspects of using Au/CeO₂ catalysts in oxidation reactions are considered. The influence of the preparation methods and synthetic parameters, as well as the characteristics of the ceria support (presence of dopin...

The “8th International Congress on Biocatalysis (biocat2016)” is part of a biennial conference series. Biocatalysis is a topic based on the edge of biology and chemistry, which brings together scientists from the life sciences, engineers and computer...

Developing cheap electrocatalysts for cathodic oxygen reduction in neutral medium is a key factor for practical applications of microbial fuel cells (MFCs). Natural hematite was investigated as a low-cost cathode to improve the performance of microbi...

Emission control catalysts constitute an essential part of today’s vehicles powered by internal combustion engines, mitigating the harmful effects of pollutants in the exhaust such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate ma...

Nano-porous anodic aluminum oxide (AAO) supported Ni-Ce mixed metal oxide catalysts were prepared and tested for dry reforming of propane to produce synthesis gas. The presence of Ce efficiently suppressed the nickel particle sintering and improved t...

An innovative nanoscale ZnO/polybutadiene rubber composite (ZBRC) was developed as a valid alternative to TiO₂ particles or immobilized TiO₂ for the mineralization of chlorinated hydrocarbons without difficulties in the recovery of nanoscale photocat...

Various porous binary oxides with elevated textural properties were obtained in this work. The as-synthesized solids were calcined or modified by reflux and extraction processes. Characterizations through SEM, nitrogen physisorption and TEM technique...

Every four years, a group of outstanding individuals, the best in their field, come together from all over the world.

Carbon-supported Pt–Ru alloys with a Pt/Ru ratio of 1:1 were prepared by NaBH₄ reduction at room temperature. X-ray diffraction (XRD) measurements indicate that the as-prepared Pt–Ru nanoparticles had a face-centered cubic (fcc) structure. X-ray phot...

Lipase from Aspergillus niger was “doubly immobilized” with SiO₂ nanoparticles in sol-gel powders prepared via the base-catalyzed polymerization of tetramethoxysilane (TMOS) and methyltreimethoxysilane (MTMS). The hydrolytic activity of the immobiliz...

Petroleum, natural gas and coal supply most of the energy consumed worldwide and their massive utilization has allowed our society to reach high levels of development in the past century.[...]
