The conversion of fructose to 1,2‐propylene glycol (PG) is an important process from cellulosic biomass to high‐value added chemicals. Herein, Ru‐WO_x/hydroxyapatite (HAP) catalyst was employed for this reaction and reached up to 91.3% yield of PG at 180 °C, 1 MPa initial hydrogen for 8 h in water. On this catalyst, Ru and WO_x were highly dispersed on HAP support and they interacted with each other to form a special catalytic center. The lack of isolated Ru or RuW alloy site led to a moderate activity for hydrogenolysis and hindered the further conversion of PG to propanol. The weak basic HAP support efficiently prevented the humin formation. This precisely controlled catalyst has potential in green PG production.

Ru-WOx /羟基磷灰石催化剂对果糖的选择性化学催化转化为1,2-丙二醇†

果糖向1,2-丙二醇（PG）的转化是从纤维素生物质到高附加值化学品的重要过程。本文中，Ru‐WO _x /羟基磷灰石（HAP）催化剂用于该反应，在180°C，1 MPa初始氢气在水中8小时的条件下，PG的收率达到91.3％。在此催化剂上，Ru和WO _x高度分散在HAP载体上，它们彼此相互作用形成一个特殊的催化中心。缺乏孤立的Ru或RuW合金位点导致适度的氢解活性，并阻碍了PG进一步转化为丙醇。弱的基本HAP支持有效地阻止了人源素的形成。这种精确控制的催化剂在绿色PG生产中具有潜力。
