We report a novel synthesis of stable doped solid carbon monoxide (p-CO) via hard x-ray irradiation of strontium oxalate at ambient conditions and high pressure. We also show via mid- and far- infrared (IR) techniques that CO₂ produced via x-ray photochemistry remained trapped within the recovered sample for many months in contrast to pure p-CO which decomposes in days. Our results demonstrate that p-CO doped with carbonates (as verified with IR and Extended X-ray Absorption Fine Structure spectroscopies) is relatively stable, enabling longer term and practical use of this novel material for CO₂ storage or as a novel electrical/optical material.

X射线诱导的新型材料合成：在环境条件下稳定的，掺杂的固体CO。

我们报告了通过在环境条件和高压下对草酸锶进行硬X射线辐照来稳定掺杂固体一氧化碳（p-CO）的新型合成方法。我们还通过中红外和远红外（IR）技术表明，与纯p-CO（在几天内分解）相反，通过x射线光化学法产生的CO ₂仍被困在回收的样品中长达数月之久。我们的结果表明，掺有碳酸盐的p-CO（经IR和扩展X射线吸收精细结构光谱学验证）相对稳定，可以长期和实际使用这种新颖的材料进行CO ₂储存或用作新颖的电/光器件材料。
