The catalytic hydrogenation of organic substrates containing {many|numerous|several|a lot of|quite a few|lots of} unsaturated functional groups {is an|is definitely an} {important|essential|crucial|critical|significant|vital} step {in the|within the|inside the} industrial preparation of fine {chemicals|chemical substances|chemical compounds} and has {always|usually|often|constantly|generally|normally} been a hot spot in {basic|fundamental|simple|standard} catalysis {research|study|analysis|investigation}. {For example|For instance|As an example|By way of example|One example is}, the phenethyl alcohol obtained by the preferential hydrogenation {of the|from the|in the|on the|with the|of your} C=O group of acetophenone {is a|is really a|is actually a|can be a|is often a|is usually a} {valuable|beneficial|useful|worthwhile|precious|important} intermediate for the production of spices, flavors, and medicines. {Furthermore|Moreover|In addition|Additionally}, {as the|because the} demand for 1-phenylethanol (PhE) continues to {increase|improve|boost|enhance|raise}, the catalytic hydrogenation of acetophenone (AP) is becoming {more|much more|a lot more|far more|additional|extra} {and more|and much more} {important|essential|crucial|critical|significant|vital}. The hydrogenation of acetophenone {is a|is really a|is actually a|can be a|is often a|is usually a} {complex|complicated} multi-step reaction. At present, {relatively|fairly|comparatively|reasonably|somewhat} {few|couple of|handful of} catalytic systems are {used|utilized|employed|utilised|applied|made use of} {in this|within this} reaction. The enantioselective hydrogenation on heterogeneous catalysts is {due to|because of|as a result of|on account of|resulting from|as a consequence of} its inherent operational and {economic|financial} {advantages|benefits|positive aspects}, {such as|like|including|for example|for instance|which include} the atomic economy. {It is|It’s|It really is|It truly is|It can be|It is actually} {one of the most|probably the most|just about the most} {ideal|perfect|best|excellent} {methods|techniques|strategies|approaches|procedures|solutions} {as it|because it|since it} {is easy|is simple} to separate and recycle the catalyst. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, the {traditional|conventional|standard|classic|regular} synthesis way in batch reactors {usually|generally|typically|normally|commonly|ordinarily} {takes|requires} a {long|lengthy|extended} time with an unsatisfying conversion {which is|that is|which can be} not conducive to industrialization. Heterogeneous non-precious metal catalysts are advantageous for their implementation in flow reactor systems for industrial applications {due to|because of|as a result of|on account of|resulting from|as a consequence of} their ease of separation, low {cost|price|expense}, and environmental protection. Herein, we report {the first|the very first|the initial} use of non-noble metal Ni-supported graphene-based catalysts for hydrogenation of acetophenone to phenylethanol with {high|higher} efficiency {in the|within the|inside the} flow reactor which can {significantly|considerably|substantially|drastically} {improve|enhance|boost|increase|strengthen} mass and heat transfer. The conversion {rate|price} {after|following|right after|soon after|immediately after|just after} optimizing the reaction {conditions|circumstances|situations} {can be|may be|could be|might be|is often|is usually} as {high|higher} as 99.14% {with a|having a|using a} satisfactory conversion {rate|price} of 97.77%. This catalyst is magnetic and has {good|great|excellent|very good|fantastic|superior} cyclability. {After|Following|Right after|Soon after|Immediately after|Just after} 48 hours of uninterrupted continuous experiments, the Ni-based catalyst {still|nonetheless|nevertheless} maintains {high|higher} catalytic activity, the conversion {rate|price} {still|nonetheless|nevertheless} reaches 88.44%, {and the|and also the|as well as the|along with the|plus the} catalyst structure remains intact and {stable|steady}.
