Due to the high porosities, large surface areas, insolubilities in solutions, and unique structural and morphological structures, porous materials are utilized in various application areas such as energy conversion and storage, wastewater treatment, adsorption, catalysis and photocatalysis. In this study, activated carbons (QCACs), one type of porous materials, were synthesized from Quercus cerris acorn shells by using ZnCl2 chemical activation under various production conditions. The effects of carbonization temperature, carbonization period, and impregnation ratios on the yields, surface areas, pore developments, and N2 adsorption–desorption isotherms of activated carbons obtained were investigated in detail. The highest surface area (1751.61 m2/g) was reached when utilized at the impregnation ratio of 2.0 at 500 ℃ for 90 min. The total pore volume of QCAC increased with increasing impregnation ratio, however the micropore volume of QCAC reduced. It was found from the pore distribution data that QCACs contained mostly narrow mesopores and a little amount of micropores. Also, N2 adsorption–desorption isotherm data revealed that QCACs produced under different conditions were usually mesopore structures, and the pores were narrow slit-shaped. Moreover, the data provided from SEM, FTIR, Boehm titration, and elemental analysis gave more characterization information about QCACs synthesized.

This review aimed to present a general framework of some recent research trends and highlights reflecting the current status of durian waste valorization opportunities, applying the descriptive approach. In this regard, research was conducted on the keywords “durian waste” among the most used scientific databases, and the selected and included scientific publications are far from exhausting all the available and accessible literature on the subject under consideration, the complete detailed bibliographic description of which is beyond the scope of the present review. At the forefront, as a priority in many of the diverse researches, is the pursuit of achieving basic circular goals and sustainable principles related to reducing the total amount of durian waste, the search for effective methods for their safe treatment and storage, the development of methods to add value, the implementation of strategies to transform those considered as waste into useful raw materials and resources that can be subjected to recovery to obtain material goods with a view to their effective ecological valorization. As a result of the literature survey, among the main areas that are intensively worked on in the current conditions for the utilization of durian waste, the following could be mentioned: chemical compounds extraction and bioactivity characterization; activated carbon and sorption properties; nanoparticles; anaerobic digestion and biogas production; biodiesel; bioethanol; briquettes and pellets; ink; packaging; animal feed; food systems; as well as some other valorization directions and research tendencies. Conducting numerous studies in such diverse directions shows the overall importance for society of the subject under consideration, related to the proper treatment of durian waste, the application of appropriate strategies for their effective and successful utilization, emphasizing the need to summarize and systematize the recent state in the current progress regarding the valorization of durian waste, which allows and enables periodic renewal and updating of information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
