Overview

What is he best known for?

The fields of study he is best known for:

  • Catalysis
  • Organic chemistry
  • Oxygen

José J.M. Órfão spends much of his time researching Catalysis, Inorganic chemistry, Activated carbon, Adsorption and Carbon. The concepts of his Catalysis study are interwoven with issues in Carbon nanotube, Oxygen and Mineralization. His biological study spans a wide range of topics, including Aniline, Reactive dye and Catalytic oxidation.

His Activated carbon study introduces a deeper knowledge of Organic chemistry. His work investigates the relationship between Adsorption and topics such as Thermal treatment that intersect with problems in Dye molecule and Cationic polymerization. José J.M. Órfão brings together Carbon and Spectral line to produce work in his papers.

His most cited work include:

  • Modification of the surface chemistry of activated carbons (2186 citations)
  • Pyrolysis kinetics of lignocellulosic materials—three independent reactions model (608 citations)
  • Adsorption of anionic and cationic dyes on activated carbons with different surface chemistries. (544 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of study are Catalysis, Inorganic chemistry, Activated carbon, Carbon and Adsorption. José J.M. Órfão has included themes like Oxalic acid, Carbon nanotube and Mineralization in his Catalysis study. His Inorganic chemistry research incorporates themes from Bimetallic strip, Oxide, Catalytic oxidation and Nitrogen.

His Activated carbon course of study focuses on Ozone and Sulfur. When carried out as part of a general Carbon research project, his work on Carbon nanofiber is frequently linked to work in Filamentous carbon, therefore connecting diverse disciplines of study. His work deals with themes such as Peroxide, Hydrogen peroxide and Nuclear chemistry, which intersect with Adsorption.

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Catalysis, Cellulose, Adsorption, Carbon and Carbon nanotube. Organic chemistry covers José J.M. Órfão research in Catalysis. His research in Adsorption intersects with topics in Inorganic chemistry, Ethyl acetate and Nuclear chemistry.

His primary area of study in Inorganic chemistry is in the field of Cerium. He has included themes like Coke, Oxidative phosphorylation, Raman spectroscopy and Glycerol in his Carbon study. His work in Bromate covers topics such as Titanium dioxide which are related to areas like Activated carbon.

Between 2016 and 2021, his most popular works were:

  • Carbon supported Ru-Ni bimetallic catalysts for the enhanced one-pot conversion of cellulose to sorbitol (49 citations)
  • Effect of cobalt loading on the solid state properties and ethyl acetate oxidation performance of cobalt-cerium mixed oxides. (38 citations)
  • Catalytic reduction of bromate over monometallic catalysts on different powder and structured supports (28 citations)

In his most recent research, the most cited papers focused on:

  • Catalysis
  • Organic chemistry
  • Oxygen

José J.M. Órfão mainly focuses on Catalysis, Adsorption, Inorganic chemistry, Cellulose and Sorbitol. His Catalysis research integrates issues from Activated carbon, Ethyl acetate, Carbon nanotube and Nuclear chemistry. His Activated carbon research is multidisciplinary, relying on both Heterogeneous catalysis, Bimetallic strip, Carbon and Nickel.

The various areas that José J.M. Órfão examines in his Adsorption study include Oxide, Cobalt, Oxygen, Atomic ratio and Catalytic oxidation. His study of Cerium is a part of Inorganic chemistry. His Sorbitol research is multidisciplinary, incorporating perspectives in Polymer chemistry, Thermogravimetry, Crystallinity, Tissue paper and Cellulosic ethanol.
