Catalyst
nanoparticles were synthesized using a novel “Cellulose Assisted Combustion
Synthesis (CACS)” technique. In this technique, an aqueous solution of metal
nitrate and a reducing agent is impregnated on a thin cellulose paper as
depicted in figure below1. The paper is dried and
locally ignited at one end to start combustion reaction that is self-sustained
under optimum loading of reactive solution, continuously producing
nanoparticles. The thin film helps in generating a quenching effect and limits
nanoparticles sintering in post-combustion stages. This paper describes the
synthesis of Cu, Ni and Co based nanomaterials that are found to be active for
ethanol hydrogen production2. A detailed mechanistic
study of nanoparticle evolution during synthesis process was conducted along
with the reaction pathway analysis for hydrogen production from ethanol.
In-situ DRIFTS studies on the metal surfaces reveal the differences in their
catalytic performance and helps in explaining the observed product distribution2.
