Recently, photocatalytic technology is considered to be a new technology of great interest to scientists and engineers for a wide variety of applications, including medicine, agriculture, energy, etc. Besides, photocatalytic technology has been demonstrated to be a green and effective technology for environmental treatment. In the environmental field, photocatalytic purifies greenhouse gas and Toxic in the air and water, reducing heat gain in the buildings. The appearance of nanoparticles is a new step for photocatalytic technology, it has contributed to increasing photocatalytic efficiency, supporting the application of nanomaterials in general processing environments. In the photocatalytic process, catalysts are excited by a suitable light source to produce photocatalytic reactions, the catalysts are not consumed during the reaction, which is an advantage of the photocatalytic technology when compared to other waste treatment methods such as adsorption, absorption, and filtration, etc. In addition, there are several other advantages of photocatalytic that have been noted and evaluated as having potential applications for the handling of environmental contaminants such as high reusability and decomposition efficiency, stability, low cost, simplicity of production, and use. Due to their advantages. Based on its benefits, we have begun research and application of photocatalytic agents to treat air pollution and wastewater in environmental matters, and our research includes the synthesis of new materials, enhancing and improving the functionality of commercial materials, which will be used in air pollution and wastewater treatment. For the air pollution treatment, we focus on NOx and VOCs treatment by photocatalyst under solar-light and visible light. For the wastewater treatment, we focus on commercial dyes which are used in the textile industry and heavy metal waste from the metallurgy industry. Besides, we are focusing on the modification of photocatalyst membrane reactor (PMRs), in this work, we modified and produce the new PMRs for real application in the environmental field. In addition, we also expand relationships with laboratories inside and outside Taiwan, especially, in Vietnam, Indonesia, and China. Here are some of our interesting research-topic, which had been accepted and published in the prestigious professional journals based on Wed of Science (WOS) as below:

• Etc…

         However, the practical application of nanoparticles is still very limited such as complex fabrication methods, and low durability, affecting the health of users due to the ingredients of photocatalyst are semiconductors and metals. In addition, most of these photocatalytic nanoparticles are incapable of decomposing toxic substances in visible light, which is a cause of the catalytic limitations for real-world applications. In this context, we are modifying and producing new catalysts for real-world applications. As environmental scientists and environmental engineers, we are developing the following new photocatalytic systems and new generation photocatalytic-nano and microparticles. Our framework is as below:
