Nurhidayatullaili Muhd Julkapli, Associate Professor, Nanotechnology and Catalysis Research Center, University of Malaya, Malaysia
Assoc Prof Dr. Nurhidayatullaili Muhd Julkapli is one energetic, highly determined, proactive, and a young researcher at the Universiti Malaya (UM). Holding the title of Assoc Prof and principal investigator of Nanotechnology and Catalysis Research Center (NANOCAT), UM, the nominee has demonstrated her continuous effort and contributions to the development of green photocatalyst water treatment system. Her background in Bachelor of Technology (Bioresources), Master in Material Engineering, and Ph.D. in Biopolymer has opened her mind to the benefits and significance of science and technology for human survival and population. The field of nanocatalysis has had explosive growth during the past decade. Nanoparticles have a large surface-to-volume ratio compared to bulk materials. Thus, her research works in nanotechnology and nanoscience is expected to have a great impact on the development of new catalysts. As an enthusiastic researcher in nanotechnology in catalysis, environmental and smart materials, she published 82 ISI papers with 72 % of them as corresponding and/or first author, 25 % (Q1 and Q2), 75 % (Q3 and Q4). Furthermore, she composed an academic book entitled "Nanocatalysts in Environmental Applications (2018)" published by Springer, with eight chapters of books and 20 conference proceedings. Thus, it leads to her latest h-index of 25, ih-index of 53, with the citation of 2752.
Summary
Photocatalysis is a flexible and efficient disinfection technique that may be used in a variety of applications in both air and water matrices. In the presence of light, oxygen, and moisture at ambient pressure and temperature, the process allows materials to dissolve surface-adsorbed dirt or pollutants through photooxidation and photoreduction processes. Simultaneously, renewable resources play a critical role in technological advances that promote beneficial, long-term progress in society. Renewable materials have long astonished the scientific community. This special issue is emphasizing the use of renewable materials as a major or counter component for synthesizing green photocatalyst in its many applications, taking inspiration from both directions of sustainable research activities. The synthesis of photocatalysts from renewable materials will be the focus of this special issue. At these points, the influence of various synthesis parameters at varying levels on photocatalyst yield and selectivity will be tuned accordingly. The synthesis of photocatalysts from renewable materials will be the focus of this special issue. At these points, the influence of various synthesis parameters at varying levels on photocatalyst yield and selectivity will be tuned accordingly. The second part of the special issue is on the properties as well as the characteristic including charge carrier, phase transformation, electron-hole stability, biodegradability, surface charge, conductivity, electron shutting, adsorption sites, reservoir properties, light sensitivity, thermal, element composition, active surface, particle size and morphological of the renewable materials will be discussed in detail. Effect on surface modification of renewable materials such as coupling, grafting, doping, or hybridization on the final characteristics of the catalyst is also one part of the interest in this topic. Finally, the confirmation of its catalytic activities towards a number of applications such as water treatment and energy production. In the end, the future trend, challenges, and opportunities of the photocatalysis system by renewable materials will be elaborated on and recommended.
