We present here a study of the production of furfural from xylose and wheat straw using the chromium phosphate (CrPO₄) with Lewis and Brønsted acidity as a highly efficient catalyst in the water/tetrahydrofuran (THF) biphasic system. The effects of various reaction parameters including reaction temperature, reaction time, system, and catalyst dosage were explored to evaluate the product yield. Under CrPO₄ catalysis, an excellent furfural yield could reach 88% from the xylose at 160 °C for 60 min. Meanwhile, 67% furfural and 32% 5‑hydroxymethylfurfura (HMF) were simultaneously achieved from wheat straw at 180 °C for 90 min. Mechanistic studies suggested that the perfect catalytic activity of CrPO₄ was due to its inherent bifunctional catalysis activity. It was found that the CrPO₄ was easily to be recovered and a great catalytic activity was available after four cycles, which not only contributed to a sustainably reduced energy consumption on catalyst recovery, but also reduced the concerns associated with toxic chromium element.

在此，我们对使用木糖和小麦秸秆生产糠醛的研究进行了研究，使用磷酸铬（CrPO ₄）并具有路易斯和布朗斯台德酸度作为水/四氢呋喃（THF）双相系统中的高效催化剂。探索了反应温度，反应时间，体系和催化剂用量等各种反应参数对产物收率的影响。在CrPO ₄催化下，木糖在160°C下60 min的优良糠醛收率可达88％。同时，在180°C下90分钟从小麦秸秆中同时获得67％糠醛和32％5-羟甲基糠醛（HMF）。机理研究表明，CrPO ₄具有完美的催化活性是由于其固有的双功能催化活性。发现CrPO ₄易于回收，并且在四个循环后具有良好的催化活性，这不仅有助于可持续降低催化剂回收的能耗，而且减少了与有毒铬元素相关的担忧。
