摘要

通过在磁性纳米粒子接枝活性炭的核壳结构表面上官能化磺酸基（-SO3H），有效合成了磺化磁性碳质催化剂（Fe3O4@AC-SO3H），并对其进行了 SEM、XRD 和 FT-IR 分析。As 制备的催化剂可以在较短的反应时间内将生物质水解为糖。催化剂剂量、反应温度和持续时间等水解因素对石榴皮废料的水解均有显著影响。催化剂可在 140°C 的温度下，在 2 小时内从酸预处理过的石榴皮废料中释放出 46% 的 TRS。这种催化剂可使用磁铁轻松再生，并可重复使用多达三个周期，稳定性也得到了提高。

Hydrolysis of Fruit Waste to Reduce Sugars Using Sulphonated Magnetic Carbonaceous Catalyst

The sulphonated magnetic carbonaceous catalyst (Fe3O4@AC-SO3H) was effectively synthesised by functionalising the sulphonic acid group (–SO3H) on the surface of the core-shell structure of magnetic nanoparticle grafted activated carbon and analysed by SEM, XRD, and FT-IR. The As-prepared catalyst may aggressively hydrolyse biomass to sugar in a shorter reaction time. Hydrolysis factors such as catalyst dose, reaction temperature, and duration all had a significant impact on the hydrolysis of pomegranate peel waste. The catalyst could liberate 46% of TRS in 2 hours at 140°C from acid-pretreated pomegranate peel waste. This catalyst can be easily regenerated using a magnet and reused for up to three cycles with improved stability.

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
