Metal-based aerogels have attracted numerous studies due to their unique physical, structural, thermal and chemical properties. Utilizing aluminum waste, a facial, environmentally friendly approach to aluminum aerogels is introduced. Aluminum powder, with poly(acrylic acid) and carboxymethyl cellulose as binders, is converted into the aluminum aerogels using the freeze-drying method without...

A series of Al-doped ZnO nanoparticles with different Al content was synthesized via a solvothermal route, and employed as photocatalysts for the degradation of the organic dye Rhodamine B in liquid phase under UV and visible-light irradiation. The amount of dopant incorporated into the final solid was quantified by inductively coupled plasma-optical emission spectrometry (ICP-OES). It showed...

As carbon dioxide and the green house effect caused by it, is of major concern for humanity, countless efforts are made to provide solution. One route is to convert the excess carbon dioxide into valuable feedstock materials for the chemical indsutry. Since the stability of carbon dioxide necessitates the use of catalysts, interest is high in development and improvement of catalytic materials...

We report on a novel sol-gel approach to synthesize highly porous alumina. Herein, an aluminum alkoxide is employed as a second homonuclear precursor alongside an aluminum salt. The use of carcinogenic epoxides can thus be avoided.
To date, the most well-established approach for the sol-gel synthesis of porous alumina is found in the epoxide-mediated route, starting from an aluminum salt. In...

With the increasing energy demand, the replacement of unsustainable fossil fuels with renewable sources of energy is desperately needed. Solar fuels, such as hydrogen (H2) are one of the most promising alternative energy sources. The ample supply of water and sunlight on earth makes hydrogen generation via the photo-catalytic water splitting reaction a viable source. Although the earth...

Introduction

Chemical fixation of CO2 and its utilization as C1 building block into fine chemicals are among key areas ofresearch to mitigate this greenhouse gas. One strategy is to use catalysts to form cyclic organic carbonates bycoupling reaction between CO2 and epoxides. These organic compounds are very interesting in industry dueto their enormous scope of applications [1]. Since...

The ever-increasing energy consumption by human societies leads to the unprecedented need for green and renewable fuels. Hydrogen is a suitable alternative, however still today the most cost-effective source remains from fossil fuels. Photocatalysis, is a promising strategy to generate hydrogen from renewable sources, such as water and sunlight. However, the efficiencies are not yet enough to...

Hydroxyapatite (HAP) has been used more and more as a catalytic media for the conversion of ethanol1, such as converting ethanol to n-butanol, converting ethanol to butadiene, using apatites doped with Sb and Mn5. In this context, the present work aims to develop catalysts, using the HAP obtained by sol - gel method, using eggshell as a source, to be used in the conversion of ethanol into...

Technologies for exhaust gas treatment in combustion processes are diverse. A major focus in the development of novel catalysts lies on cost reduction by lowering the precious metal content while maintaining the catalytic activity, e.g. by using transition metal oxides. Such porous materials with integrated catalytically active compounds for heterogeneous catalysis play a crucial role in...

Methane, the main component of biogas, can be used for the production of heat, electricity, and chemicals. The reaction of methane oxidative coupling (OCM) is a promising process that can produce value-added products (ethylene and ethane) via the direct conversion of methane. Normally, the direct gas-phase reaction of OCM can occur at high temperatures (> 700 °C). However, the chemical...
