This work uses thermal polymerization of urea nitrate, oxyacetic acid and urea as the raw material to prepare ultra-thin porous carbon nitride with carbon defects and C-O band（OA-UN-CN）. Density functional theory（DFT） calculations showed OA-UN-CN had narrower band gap,faster electron transport and a new internal construction electric field. Additionally, the prepared OA-UN-CN significantly enhanced photocatalytic activation of peroxymonosulfate（PMS） due to enhanced light absorption performance and faster electron overflow. As the result, the OA-UN-CN/PMS could entirely degrade bisphenol A（BPA） within 30 min, where the photodegradation rate was 81.8 and 7.9 times higher than that of g-C3N4and OA-UN-CN, respectively. Beyond, the OA-UN-CN/PMS could likewise degrade other bisphenol pollutants and sodium lignosulfonate efficiently. We suggested possible photocatalytic degradation pathways accordingly and explored the toxicity of its degradation products. This work provides a new idea on the development of advanced photocatalytic oxidation processes for the treatment of bisphenol pollutants and lignin derivatives, via a metal-free photothermal-catalyst.

政党主体性是指政党具有主导性地位、自主性特质和能动性作用。与工具型中介组织定位的西方政党不同,中国共产党展现出鲜明的政党主体性。从政党地位来说,中国共产党既是缔造国家又是组织社会的主体力量,由此形成了一种以政党为中心的主导性结构。从政党组织来说,中国共产党在思想、意志和行动上表现出了自觉主动性、独立自主性和自我革命性等政党自主性特质。从政党能动性来说,中国共产党不仅以政党建设驱动国家建设、引领社会治理,还为社会主义现代化建设事业提供一种政党动力,赋予中国式现代化鲜明的中国特色。

长期以来,受观念、制度、程序等因素影响,对法律进行合宪性审查的制度推进较为缓慢。在党的二十大报告正式提出“健全保证宪法全面实施的制度体系”的背景下,落实对法律的合宪性审查,从学理上还是实践中对于完善我国的宪法监督制度都具有重大的意义。要依托法律草案合宪性说明制度,强化对法律草案的合宪性审查工作,还要根据我国宪法监督体制对法律实施阶段的合宪性审查设计科学、合理、可行的机制和程序,构建从事前到事后的全过程的合宪性审查环节,实现对法律是否合宪的有效监督。对法律的合宪性审查有利于保障宪法权威和法治统一,推进宪法全面实施,加快建设社会主义法治国家。

通过法律具体化宪法精神、原则和规定并加以实施一直被视作实施宪法的一种重要方式。宪法实施和法律实施都是将规范要求贯彻落实到具体的社会生活中的实施活动。表面看起来具有相似性,但是由于宪法特殊的性质、功能和价值目标,宪法实施与法律实施不能划等号。法律实施规范前提的不足和法律实施的结构性缺陷让法律实施难以独自保证宪法实施的质量和效果。何况宪法实施所依靠的实施方式、路径是多元的,除了法律实施,宪法还依靠直接实施和政治实施来确保实施的全面性与效果。不过,以法律实施推动宪法实施具有极其重要的意义,法律实施要以宪法价值、原则和精神作为指导,以保障基本权利为最高价值目标,在健全保证宪法实施的体制机制中更好发挥法治化实施路径中的主渠道作用。
