挥发性有机物(VOCs)是大气污染物的主要组分之一,具有毒性,易对环境和人体健康产生威胁,因此受到广泛关注。目前,催化氧化法是有效降解VOCs的方法之一。光催化具有价廉、无毒、节能和高效等优势,逐渐成为研究重点。过渡金属氧化物凭借抗中毒、热稳定性好、使用寿命长、对氧化反应的选择性高等优势,成为去除VOCs催化剂的绝佳候选者。多孔结构可以扩大催化材料的比表面积,增加活性位点,更好地促进VOCs的催化降解。本文综述VOCs的去除方法,分析催化剂的选择,展望技术发展方向,以期更好地利用多孔过渡金属氧化物作为光催化剂,有效去除VOCs,保护大气环境。 相似文献

基于2000—2021年智慧芽数据库收录的稀土产业链有关专利数据,利用社会网络分析方法和Gephi软件的可视化分析,从稀土产业链的开采、冶炼、精加工以及应用4个环节分析稀土专利技术趋势,为稀土技术发展提供借鉴。结果表明:从时间趋势来看,总体呈上升趋势,但稀土冶炼环节专利数量波动较大,稀土开采与精加工环节增长缓慢;从专利授权机构来看,江西理工大学、江西稀土金属钨业有限公司在采矿阶段专利授权量排名靠前,主要集中于矿产资源附近,而其他环节主要以日本、韩国和德国的机构为主;从专利授权机构合作网络来看,发现国外的公司与机构之间合作密切,而中国科研院所间缺乏协作;从热点技术领域来看,C22C59/00、C22C38/00、H01F/057、H01F41/02、B22F1/00等技术领域密度较大且处于核心位置。 相似文献

本文将专利竞争力划分为现实竞争力与潜在竞争力两个层次,从专利拥有、运营、保护、服务、投入、创造和管理七个方面构建专利竞争力指数,对中国省际专利竞争力进行测算,结果显示,中国现阶段区域专利竞争力总体水平不高,而且省际之间差距很大。本文将所选取的31个省、直辖市、自治区的专利竞争力划分为三类:第一类为现实竞争力和潜在竞争力均高于国内平均水平的地区,此类地区可通过打造服务助力型政府、激励企业丰富专利拥有和专利运用方式来提升专利竞争力;第二类为专利现实竞争力不强,但有较强的潜在竞争力的地区,此类地区的政府在培育专利竞争力方面应定位于规划、布局和引导,企业则应转变观念,树立专利是市场竞争有效武器的观念;第三类为专利现实竞争力和潜在竞争力均很弱的地区,此类地区需要主导推动型的政府来推动地区专利竞争力的提升。 相似文献

The economic arguments for patents are that: (i) they are a necessary incentive to inventive industry; (ii) they are a sufficient stimulus to technological innovation and investment; (iii) the monopoly privileges granted to the patentee are compensated for by the disclosure of technical information to society. The paper shows all three propositions to be of dubious validity in the developing-country context. At least five-sixths of patents in developing countries are in foreign hands, mainly transnational corporations, and thus bear no relation to the flow of domestic inventive activity. At least 95 per cent of patents in developing countries are never used and serve as a block to domestic production while increasing the market power of foreign corporations. Those patents actually in use impose substantial costs both through ‘transfer-pricing’ and restrictive clauses in licensing agreements. Finally, technical information in patent documents is of limited value to developing countries and could in any case be obtained cheaply in the absence of patents. 相似文献

Impacts of the Japanese patent system on productivity growth 总被引:1,自引:0,他引:1
We investigate empirically how the Japanese patent system has affected post-war growth in Japanese total factor productivity. The system has been criticized for several reasons, including that it encourages numerous filings of narrow claims that build incrementally on fundamental technologies developed by domestic and foreign inventors. Stated in different terms, the system was designed to promote technological catch-up and diffusion through incremental innovation. However, its effectiveness in achieving this purpose has not been studied systematically. We provide econometric evidence that the technology diffused through the Japanese patent system had a significant and positive impact on Japan's technical progress. 相似文献

ABSTRACTThe article analyses Swedish and Finnish patent agents and their businesses at the turn of the twentieth century. Due to legal requirements, all foreign patent applications had to pass through the hands of patent agents. Despite the central role, this transnational business of technology intermediation has received only limited attention in the scholarship. The article studies the business relationships between the patent agents and their clients, and employs new datasets, which include information about all foreign patentees using a patent agent in 1860–1910. The main findings are that the transnational business relationships affected the specialisation of national patent agents, especially in Finland, where patent agents with a legal background contributed to the inflow of inventions managed by Swedish patent agents. Patent agent services also represented significant indirect costs of the patent systems for their foreign clients. 相似文献

Because China has become one of the largest applicants of PCT patents, it is of interest to compare the quality of Chinese and non-Chinese applications. We extend a quality index based on internationally comparable citation data from international search reports (ISR) to consider foreign, domestic, and self citations. Whereas foreign citations show that Chinese PCT patent applications reach only a third of the non-Chinese quality benchmark, the extension towards domestic and self citations suggests a higher quality level that converges to or even surpasses the benchmark. We investigate these differences based on firm-level regressions and find that in China, only foreign citations, but not domestic and self citations, have a significant and positive relation to R&D stocks. Using Germany as a representative country without policy support for patenting, we show that all three citation types may be used as economic indicators if policy distortion is not a concern. Our results show that domestic and self citations suffer from an upward bias in China and should be employed with caution if they are to be interpreted as a measure of patent quality. 相似文献
