浅析地面辐射采暖的应用和推广

随着建材工业的迅速发展，新型保温材料和交联聚乙烯管的应用，地面辐射采暖应运而生。地面辐射采暖即适应人体对热量的要求，并提高了人们生活质量和环境质量，节约了能源，同时也解决了分户计量的问题，是一项新技术、新产品应用在供热行业的具体体现。目前，热费收缴困难摆在主要供暖大中城市面前，由于传统单一供热方工式，各业主交费好的与不交费的用户难以在供热效果上有所区别。

介绍了地面辐射供暖的发展概况、系统型式、构成特点、施工及推广,通过目前地面辐射供暖中存在的几个问题及改进方法,阐述了地面辐射供暖的优缺点和发展方向。

Synthesis of Ag/AgCl/Fe-S plasmonic catalyst for bisphenol A degradation in heterogeneous photo-Fenton system under visible light irradiation

A novel plasmonic photo‐Fenton catalyst of Ag/AgCl/Fe‐S was synthesized by ion exchange and photoreduction methods.The obtained catalyst was characterized by X‐ray diffraction,X‐ray photoelectron spectroscopy,scanning electron microscope imaging,and Brunauer‐Emmett‐Teller measurements.Moreover,the photocatalytic activity of Ag/AgCl/Fe‐S was investigated for its degradation activity towards bisphenol A(BPA)as target pollutant under visible light irradiation.The effects of H2O2concentration,pH value,illumination intensity,and catalyst dosage on BPA degradation were examined.Our results indicated that the Ag/AgCl material was successfully loaded onto Fe‐sepiolite and showed a high photocatalytic activity under illumination by visible light.Furthermore,active species capture experiments were performed to explore the photocatalytic mechanism of the Ag/AgCl/Fe‐S in this heterogeneous photo‐Fenton process,where the major active species included hydroxyl radicals(?OH)and holes(h+).
