The development of catalysts capable of converting CO2 into usable energy remains a key challenge toward achieving carbon neutrality. Hydrogen boride (HB), a two-dimensional material composed of positively charged hydrogen and a negatively charged boron network, has been reported to convert CO2 to hydrocarbons when heated with CO2. Additionally, HB aqueous dispersions show acidity, and neutralization with basic solutions is expected to yield HB-based materials doped with hetero-elements, potentially enhancing catalytic properties by tuning electronic structures. However, no prior studies have demonstrated this approach for elementally doped HB. In this work, potassium-doped HB was synthesized via neutralization with potassium hydroxide. Structural and electronic features of the materials were characterized by infrared spectroscopy and X-ray photoelectron spectroscopy, and the findings will be presented and discussed in detail.
