Functional Material for Energy and Environment

Environmental and energy crisis problems become important issues in last decade, and it will get more intensive attention in the next years. Due to this background, functional material development for the energy and environmental applications will be interesting and challenging topics for research activities. With the goal of green chemistry for sustainable development, the focus of research will be on the low cost technique for environmental protection including heterogeneous catalysis, photocatalysts, adsorption and nanomaterial for energy and environmental issues. Here are the detail of topics:
Heterogeneou catalysis for energy issues
In the renewable energy perspective, low cost and economic conversion of biodiesel get more attention for adaptive and applicability in small industry scale. The replacement of NaOH or KOH as homogeneous base catalysts with many heterogeneous solid acid and base catalysts have been investigated for a perspective of green chemistry, particularly for sustainable and reusable material aspects. The best way to enhance the economic value of the catalytic process for biodiesel production is to use agricultural waste as catalytic materials. Previous works reported potency of agricultural waste ash as precursor or support of catalyst for biodiesel conversion. In next years, the development of low cost catalayst for biodiesel conversion will be derived from biogenic silica-based materials, waste material from animals (CaO), and clay-based material.
Heterogeneou catalysis and intensification for sustainable reaction
Another chance for greener reaction enhancement will be attempted by developing heterogeneous catalyst and intensification using simpler and energy efficient process such as microwave (MW) irradiation, sonocatalytic and tandem reactions.

Photocatalysis
Dyes removal from wastewater is the main problem encountered in textile industry, instead of fate organic contaminated water. Color is a visible pollutant containing dyes which are organic compounds and therefore, it is required that the organic contamination in effluents be treated before they are discharged into aquatic environment. In this field of research a novel technology to remove the contaminants by advance oxidation process (AOPs) by using Photo-Fenton like process was widely developed. Photocatalysis utilizing titanium dioxide (TiO2) has gained great interest due to not only its high photocatalytic activity, chemical stability, and low cost but also from its band gap energy (anatase, 3.2 eV) allowable for UV excitation can be obtained from solar spectrum. Furthermore, in photo-Fenton like process, combination of photoactive material will be alternative process that can be operated in effective, easy to control and also cost efficient condition. Some effort concerned with modification of photo-Fenton catalyst with some inorganic supports were reported, and will be the focus of the research group. A wide range of solid materials, such as transition metal exchanged-zeolites and pillared clays have been reported to be active for oxidative degradation of organic compounds involved dye compounds through the photo-Fenton-like reaction.

Adsorption
Adsorption is one of the attractive methods for the removal of metal ions or organic contaminant in water environment in the terms of simplicity, suitability for low concentration, availability of different low-cost adsorbents and easy in application. Along with the need of low adsorbent, many inorganic and organic materials were developed from waste. Instead of carbon-based materials such as biochar, biosorbent and activated carbon that could be derived from agricultural waste, calcium-based materials were also widely studied.
