We successfully 3D printed Au/TiO2 monoliths for photogenerating hydrogen from water/ethanol gaseous mixtures under dynamic conditions. Monolith designs were printed by additive superposition of microfilaments of titania-based ...

Nanostructured tungsten carbide with high surface area and containing amorphous carbon is prepared by a low temperature combustion synthesis method. The nanostructured tungsten carbide is used as the catalyst in a gas ...

In this paper, we investigated the effect of reaction kinetics and moving bed reactors for chemical looping (CO2/H2O) splitting unit (CL) that produces syngas and fed back to the power plant to gain the efficiency loss due ...

A silicon micromonolith of 7 mm diameter and 0.2 mm length containing 1.5 million regular channels with a diameter of 3.3 μm was used for obtaining hydrogen through ethanol or bio-ethanol steam reforming (ESR) and oxidative ...

The steam reforming and oxidative steam reforming of dimethyl ether (DME) were tested at 573–773¿K over a CuZn/ZrO2 catalyst in microreactors with three different types of channels: ceramic square channels with side lengths ...

In this work the effect of Fe addition to copper/ceria catalysts on the catalytic activity toward CO-PROX reaction has been studied and related to the modification of textural and redox properties induced by iron. Catalysts ...

A cost-effective and scalable approach was developed to produce monodisperse Ni2-xCoxP nanocrystals (NCs) with composition tuned over the entire range (0 = x = 2). Ni2-xCoxP NCs were synthesized using low-cost, stable and ...

L’objectiu d’aquest projecte és el de desenvolupar un nou mètode de detecció de fuites externes en bescanviadors de calor per l’empresa Frape Behr, basat en la captació, en l’interior d’una cambra estanca (embolcall), ...

Hydrogen could be one the most efficient source of energy in the future. The problem which is remaining about this energy is storage. Indeed, it is still very hard to store hydrogen due to the volume that it takes in its ...

Ethanol steam reforming was performed in a catalytic membrane reactor (CMR) containing Pd-Ag membrane tubes selective to hydrogen and Pd-Rh/CeO2 catalyst. Experiments were performed at 923 K, 6-10 bar, and fuel flow rates ...
