Special Issue Information

Dear Colleagues,

We have the pleasure to announce the 1st Malaysia International Conference on Nanotechnology and Catalysis in Langkawi Island, Malaysia. The 1st Malaysia International Conference on Nanotechnology and Catalysis (MICNC2021) will be held on 1–3 September 2021 at Langkawi Island, Malaysia. The conference is hosted by Nanotechnology and Catalysis Research Centre (NANOCAT), Universiti Malaya. MICNC2021 will be a great platform for researchers, academics, students, as well as practitioners from industries to engage in knowledge and technology sharing. This conference also encourages participants to exchange experiences and challenges independently. Additionally, it promotes future collaborations and knowledge transfer between participants. It includes plenary, keynote and invited speakers, oral presentations, and poster sessions on different topics.

The present Special Issue will feature the works presented at MICNC2021 that promote the linkage of nanotechnology and catalysis but is also open to general contributions from the catalysis community. Authors with expertise in any topic of catalysis are cordially invited to submit their manuscripts to this Special Issue of Catalysts. Significant full papers and review articles are very welcome. The topics of the conference will cover various aspects among the following research areas:

  • Green synthesis;
  • Energy, oil and gas;
  • Industrial catalysis;
  • Biomaterials, polymers;
  • Nanocomposite, hybrid;
  • Colloid, surface aspects;
  • Nanocrystal, nanoparticles;
  • Nano-safety, nanomedicine;

  • Chemical kinetics and catalytic activity;
  • Sensing, separation, membrane reactor;
  • Macrocyclic and supramolecular chemistry;
  • Graphene, fullerenes, CNTs, cellulose, fiber;
  • Soft matter (aerogels, foams, granular matter);
  • Nanointegration, nanotribology, nanoreactors;

and other related areas in science and engineering.

The purposes of this study are to investigate the effect of metal (Co and Mo) impregnation to ZSM-5 catalysts on the Brønsted to Lewis (B/L) ratio as the active sites of cracking reaction, and the catalysts’ performance testing for palm oil cracking to produce hydrocarbon-rich biofuels. Both metals were impregnated on the ZSM-5 catalyst using a wet-impregnation method. The catalysts were characterized using X-ray diffraction (XRD), X-ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), Brunauer–Emmett–Teller (BET), and Pyridine-probed Fourier-Transform Infrared (Py-FTIR) spectroscopy methods. The catalysts were tested on the cracking process of palm oil to biofuels in a continuous fixed-bed catalytic reactor. In order to determine the composition of the organic liquid product (OLP, biofuels), the product was analyzed using a gas chromatography-mass spectrometry (GC-MS) method. The results showed that the co-impregnation of Co and Mo to ZSM-5 highly increased the Brønsted to Lewis acid site (B/L) ratio, although the total number of acid sites decreased. However, the impregnation of Co and Mo on the ZSM-5 decreased the surface area of catalysts due to pore blocking by metals, while the B/L ratio of the catalysts increased. It was obtained that by utilizing Co- and Mo-impregnated ZSM-5 catalysts, the hydrocarbons product selectivity increased from 84.32% to 95.26%; however, the yield of biofuels decreased from 67.57% to 41.35%. The increase in hydrocarbons product selectivity was caused by the improvement of the Brønsted to Lewis (B/L) acid sites ratio. Full article

Copper oxide (CuO) nanoparticles (NPs) were decorated on reduced graphene oxide (rGO) through the effective synthetic route method. Powder X-ray diffraction, Fourier transform infrared, ultraviolet-visible absorption, and scanning electron microscopy techniques were used to analyze the chemical structure, functional groups, absorbance, and morphology. Under visible light illumination, the CuO/rGO nanocomposites have higher catalytic activity compared to the bare CuO NPs which were suitable for degradation of methylene blue (MB) and Congo red (CR) dyes. According to the findings, the CuO/rGO nanocomposites possess excellent photocatalytic efficiency. Thus, the synthesized CuO/rGO nanocomposite is a promising photocatalyst for the deterioration of organic pollutants in water and wastewater treatment. Full article
