Diffusion and reaction in a double enzyme supported catalyst

DIFFUSION AND REACTION WITHIN A SHAPED NICKEL PEROVSKITE CATALYST

  Abstract : In this study, we prepared a LaNi0.3Al0.7O3 perovskite catalyst using a sol-gel related method (with prop ionic acid as a solvent) for use in the methane dry reforming reaction to produce synthesis gas. We defined the catalyst structure on the basis of X-ray diffraction analysis and measurements of the specific surface area and particle size distribution. The mixed oxide structure ...

Few-layered graphene-supported palladium as a highly efficient catalyst in oxygen reduction reaction.

New, active and stable catalysts competitive to Pt catalysts are necessary for fuel cell development. Here, we present few-layered graphene-supported Pd, revealing a performance superior to Pt/C and Pd/C ORR (positive half-wave potential shift E(1/2) by 50 mV, approximately one order of magnitude higher area- and mass-normalized current densities, I(area), I(mass), after 2500 cycles). The catal...

Supported employment: A catalyst for service development

KARE is a not-for-profit parents’ organisation in County Kildare, Ireland, which provides services to individuals with intellectual disabilities and their families. We currently provide services for approximately 400 individuals divided equally between children and adults. The organisation has been in existence for 30 years and from the outset, the ethos has always been to support families and ...

Experimental Analysis of a Vertical, Double-Effect Diffusion Solar Still

Simulated preparation of supported porous catalyst and evaluation of its reaction-transport properties

In this contribution, mathematical model for the description of solvent evaporation and noble metal crystallization in a porous medium is presented. The methodology is based on the volume-of-fluid method and the aim is validation of the model by comparing the numerical simulation results with analytical solutions for evaporation from a single pore and for particle growth and Ostwald ripening of...
