Short communication Hydroxyapatite supported Nickel catalyst for hydrogen production

Hydroxyapatite (HAp) supported Nickel (Ni) catalyst was prepared using wet impregnation method. A series of Ni/HAp catalysts have been prepared by varying the amount of nickel viz., 3, 6 and 12 %. The highest Brunauer-Emmett-Teller (BET) surface area of 92.18 m/g was noticed for a catalyst composition containing 3% nickel loading. The scanning electron microscopy (SEM) studies revealed a smooth...

Nickel supported on nitrogen-doped carbon nanotubes as hydrogen oxidation reaction catalyst in alkaline electrolyte

The development of a low-cost, high-performance platinum-group-metal-free hydroxide exchange membrane fuel cell is hindered by the lack of a hydrogen oxidation reaction catalyst at the anode. Here we report that a composite catalyst, nickel nanoparticles supported on nitrogen-doped carbon nanotubes, has hydrogen oxidation activity similar to platinum-group metals in alkaline electrolyte. Althou...

Light-driven hydrogen production from aqueous solutions based on a new Dubois-type nickel catalyst.

In this work, we report a new photocatalytic system that links multifunctional semiconductor nanocrystals with emerging water-soluble molecular catalysts made of earth-abundant elements for H2 generation [Ni(P2RN2R')2(BF4)2]4-, R = Ph, R' = [PhSO3]- (NiS). This noble metal free hybrid exhibits remarkable catalytic activity with a turnover number of 511 for H2 production and a photon-to-H2 conve...

Stable Hydrogen Production from Ethanol through Steam Reforming Reaction over Nickel-Containing Smectite-Derived Catalyst

Hydrogen production through steam reforming of ethanol was investigated with conventional supported nickel catalysts and a Ni-containing smectite-derived catalyst. The former is initially active, but significant catalyst deactivation occurs during the reaction due to carbon deposition. Side reactions of the decomposition of CO and CH4 are the main reason for the catalyst deactivation, and these...

Catalyst and sorbent material for the production of hydrogen

A catalyst and sorbent is disclosed which comprises pellets with an absorbent core and a protective shell with a catalyst in the shell. Such material is especially well suited for steam reforming of hydrocarbons to produce hydrogen since a reforming catalyst can be incorporated in the shell and a sorbent for the by-product carbon dioxide can be used for the core. It is also well suited for prod...
