Hydrogen boride (HB) or hydrogenated borophene sheets are recently realized two-dimensional materials that are composed of only two light elements, boron and hydrogen. However, their catalytic activity has not been experimentally analyzed. Herein, we report the catalytic activity of HB sheets in ethanol reforming. HB sheets catalyze the conversion of ethanol to ethylene and water above 493 K with high selectivity, independent of the contact time, and with an apparent activation energy of 102.8 ± 5.5 kJ/mol. Hence, we identify that HB sheets act as solid-acid catalysts.
硼氢化物（HB）或氢化硼烯片是最近发现的二维材料，仅由硼和氢这两种轻元素组成。然而，它们的催化活性尚未经过实验分析。在此，我们报告了HB片在乙醇重整中的催化活性。HB片在493 K以上能将乙醇高效选择性地转化为乙烯和水，与接触时间无关，表观活化能为102.8±5.5 kJ/mol。因此，我们确定HB片可作为固体酸催化剂。
