The Effects of Ge Substrate Surface States and Au Catalyst Layer Thickness on the Growth of Different GexOy Nanomaterials and Nanocrystals Configurations Using Vapor-Liquid-Solid Method with two Steps Temperature Mode

Received: 01 September 2022;  Published: 31 January 2023;  doi: 10.21926/cr.2301006

Abstract

Recently the GexOy nanomaterials have been studied intensively due to their interesting electronic materials, which have many particular properties and applications in nanotechnology and nano-devices fabrication. Much work has been done on many different synthesis methods and their properties of Ge and GexOy nanomaterials. However, the effects of the different Ge substrate surface states and Au catalyst l [...]

Pd-Ni-B/C Nanocatalysts for Electrochemical Oxidation of Ethanol in Alkaline Media

Received: 06 September 2022;  Published: 19 January 2023;  doi: 10.21926/cr.2301005

Abstract

This paper describes the synthesis of Pd0.70-Nix-By nanoparticles (x:y = 0.30:0, 0:0.30, 0.25:0.05, 0.20:0.10, 0.15:0.15, and 0.10:0.20) supported on carbon Vulcan XC-72 R by the chemical reduction method using ethylene glycol as a reducing agent for the study of the electrochemical oxidation of ethanol in alkaline media. Neither surfactants nor templates were used during the syntheses. The catalysts were physically characteriz [...]

Fungal Laccase-Mediated Enhancement of the Bioactivity of Green Algae Extracts

Received: 01 December 2022;  Published: 19 January 2023;  doi: 10.21926/cr.2301004

Abstract

Biomass derived from green marine macroalgae Ulva sp. is considered a rich source of bioactive compounds. In the present study, we demonstrate the increased bioactivity of a phenolic-rich extract derived from green marine macroalgae Ulva intestinalis after its treatment with fungal laccases from Trametes versicolor and Agaricus bisporus. The phenolic composition of the extract, before and after its enzymatic trea [...]

Iron Doped Titania/Polyaniline Composite: An Efficient Electrocatalyst for Hydrogen Evolution Reaction in Acidic Medium

Received: 15 September 2022;  Published: 04 January 2023;  doi: 10.21926/cr.2301002

Abstract

The development of noble metal-free catalyst for hydrogen evolution reaction (HER) is the primary challenge in fuel production to replace fossil fuels. Here, we have synthesized Fe-doped TiO2/PANI nanocomposite via facile in situ polymerization method and studied its electrocatalytic activity towards HER. The composite catalyzes HER efficiently with an overpotential value of -180 mV vs. RHE in 0.5 M H2SO4 solution to achieve th [...]

Enhancement of Fischer-Tropsch Synthesis by Periodical Draining of the Wax-Filled Pores of a Cobalt Catalyst by Hydrogenolysis

Received: 27 September 2022;  Published: 03 January 2023;  doi: 10.21926/cr.2301001

Abstract

Fischer-Tropsch reactors operated in a steady state suffer from a low pore effectiveness factor and a high methane selectivity caused by internal mass transfer limitations due to the accumulation of long-chain hydrocarbons inside the catalyst pores. Therefore, an alternating process switching between Fischer-Tropsch synthesis (FTS) and drainage of the pores by hydrogenolysis is proposed. The periodical cracking of the accumulated waxes within the (partially) filled pores, realized by a switch fr [...]
