The search for the means to convert molecular hydrogen to a metal under static conditions at high pressure is reviewed with emphasis on selected recent developments in both experimental studies and theoretical approaches. One approach suggested recently makes use of mixtures of hydrogen and suitable impurities. In these materials hydrogen is perturbed by impurities with the goal of obtaining the metallization of hydrogen at moderate pressures. This approach has also been extensively examined through the use of first-principles methods and we review this recently explored experimental approach and several theoretical studies that have provided an atomic-scale picture of the interaction of hydrogen with impurities under pressure. The objective of this novel approach is to help determine if metallization of hydrogen at pressures is attainable with currently available experimental techniques.
本文回顾了在静态高压条件下将分子氢转化为金属的方法的研究，重点介绍了实验研究和理论方法方面的一些最新进展。最近提出的一种方法是利用氢气和合适杂质的混合物。在这些材料中，杂质会干扰氢气，目的是在中等压力下实现氢气的金属化。这种方法也已经通过第一性原理方法得到了广泛的研究，我们回顾了这种最近探索的实验方法和一些理论研究，这些研究提供了在压力下氢与杂质相互作用的原子尺度图像。这种新方法的目的是帮助确定在目前可用的实验技术下，氢气在压力下是否可以实现金属化。
