金催化剂因其对深度氧化反应的抑制特性，在烯烃选择性氧化等绿色转化过程中表现出独特优势。然 而，金对氢气与氧气的活化能力有限，使其在丙烯一步环氧化等反应中的本征活性受到制约。传统双金 属合金化策略虽可提升反应速率，但往往伴随副反应的开启，导致丙烯过度加氢生成丙烷或过度氧化生 成二氧化碳。针对这一挑战，研究团队构建了一种全新的"电子围栏"策略，通过在金—分子筛界面精准 组装亚稳态铑原子层，实现对金活性位电子态的有效调控，提升了丙烯环氧化反应的活性与选择性，为 高性能选择性氧化催化剂的设计提供了新思路。 中化新网讯 近日，华东理工大学化工学院段学志教授、陈文尧特聘研究员等在金属催化剂电子结构调 控领域取得重要进展。相关成果发表在《美国化学会志》上。 ...

中化新网讯 近日，为降低对俄罗斯原油的依赖，印度石油公司宣布已根据其与哥伦比亚国家石油公司 的选择性供应协议，首次采购了哥伦比亚原油。消息人士称，此次采购的200万桶哥伦比亚卡斯蒂利亚 原油预计将于2月下旬交付。 根据2021年年底签署并逐年续签的协议，印度石油公司可选择性购买总计约1200万桶的哥伦比亚原油。 不过，该公司长期以来主要依赖俄罗斯和中东原油供应，尽管也与墨西哥、巴西等国签有类似采购协 议，但鲜少实际购买南美原油。这主要因为南美原油在与俄罗斯及中东油品的价格竞争中通常处于劣 势，只有双方在价格等条款上达成一致时，交易才会执行。 船运跟踪数据显示，由于欧美对俄制裁收紧导致供应受扰，印度去年12月从俄罗斯的原油进口量预计将 骤降至120万桶/日，为三年来最低水平。此次采购被视为印度炼油商在全球积极寻找替代原油来源、推 动供应多元化的重要举措之一。 ...
