在均相溶液中由非均相催化剂而不是金属络合物催化的氢化中仲氢诱导的极化效应的证明为基于仲氢的研究开辟了一个全新的维度，证明了其不仅适用于生产无催化剂的超极化液体和气体以及用于潜在生物医学应用的长寿命非平衡自旋态，而且还用于解决现代基础和工业催化的挑战，包括催化反应的高级机理研究和反应器的操作NMR和MRI。本文总结了在这一领域取得的进展，重点介绍了我们的同事和朋友基里尔·科夫图诺夫（Kirill V. Kovtunov）的研究成果，他的科学生涯在37岁时意外而悲惨地结束了。他在这项研究中的作用当然是至关重要的，他在国家和国际一级的联系和合作的庞大网络进一步加强。我们在2020年失去的才华横溢的年轻同事和朋友Kirill Kovtunov的科学成就包括首次展示了在非均相催化剂（如固定化金属络合物和负载金属）上氢化中仲氢诱导的核自旋极化，这是生产无催化剂超极化液体和气体的重要一步，用于生物医学应用和现代催化研究。
Demonstration of parahydrogen-induced polarization effects in hydrogenations catalyzed by heterogeneous catalysts instead of metal complexes in a homogeneous solution has opened an entirely new dimension for parahydrogen-based research, demonstrating its applicability not only for the production of catalyst-free hyperpolarized liquids and gases and long-lived non-equilibrium spin states for potential biomedical applications, but also for addressing challenges of modern fundamental and industrial catalysis including advanced mechanistic studies of catalytic reactions and operando NMR and MRI of reactors. This essay summarizes the progress achieved in this field by highlighting the research contributed to it by our colleague and friend Kirill V. Kovtunov whose scientific career ended unexpectedly and tragically at the age of 37. His role in this research was certainly crucial, further enhanced by a vast network of his contacts and collaborations at the national and international level. Scientific achievements of Kirill Kovtunov, our talented young colleague and friend whom we lost in 2020, include the first demonstration of parahydrogen-induced polarization of nuclear spins in hydrogenations over heterogeneous catalysts such as immobilized metal complexes and supported metals, an important step toward production of catalyst-free hyperpolarized liquids and gases for both biomedical applications and modern catalysis research.
