An efficient, green and reusable catalyst for organic pollutant wastewater treatment has been a subject of intense research in recent decades due to the limitation of current technologies. Cellulose based aerogel composites are considered to be an especially promising candidate for next-generation catalytic material. This project was conducted in order to evaluate the behavior and ability of green and reusable sugarcane bagasse aerogels to remove P-Nitrophesnol from waste-water aqueous. Co-Zeolitic imidazolate framework@ sugarcane bagasse aerogels composite catalysts were successfully prepared via simple in situ synthesis. The structure of hybrid aerogels and their efficient catalyst in peroxymonosulfate (PMS) activation for the degradation of p-nitrophenol (PNP) was investigated. As a result, the hybrid aerogels/PMS system removed 98.5% of PNP (10mg/L) within 60~70 min, while the traditional water treatment technology could not achieve this. In addition, through a free radical capture experiment and electron paramagnetic resonance (EPR), the degradation mechanism of PNP was investigated. Further research found that the hybrid aerogels can effectively activate PMS to produce sulfate (SO4• -) and hydroxyl (OH• ). Both of them contributed to the degradation of PNP, and SO4• - plays a crucial role in the degradative process. The most important feature of hybrid aerogels can be easily separated from the solution. The obtained results showed that the outer coating structure of cellulose can stabilize Co-ZIF and reduce the dissolution of cobalt ions under complex reaction conditions. Moreover, the prepared hybrid aerogels exhibit excellent reusability and are environmentally friendly with efficient catalytic efficiency. This work provides a new strategy for bagasse applications and material reusability.
Spiritual leadership is an emerging type of leadership that focuses on using intrinsic motivation to help subordinates achieve spiritual enrichment and thus motivate employees to work. This study adopts the method of questionnaire to investigate 886 employeess of Chinese companies in three stages, and tests the mediating effect by using the bootstrap method. Our results showed that: (1) Spiritual leadership had a positive correlation on employeess' innovative behavior; (2) both psychological capital and intrinsic motivation mediated the relationship between spiritual leadership and innovative behavior; (3) we found a sequential mediating effect between spiritual leadership and followers’ innovative behavior. The findings deepened our understanding of the psychological mechanisms by which the spiritual leadership inspires innovative behavior, and provide a practical reference for managers to stimulate individual innovative behavior.
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.
