1-페닐프로판올의 수소화 분해 반응을 통해 제조된 프로필벤젠은 더 큰 시장 규모를 형성하여 상업적 활용 가능성 이 높다. 이러한 가운데 질소가 도핑된 탄소(NC)는 물리적 및 화학적 특성이 크게 변경될 수 있어 수소화 분해 반응의 촉매 지지체로 많이 사용된다. 본 연구에서는 멜라민과 탄소의 질량 비가 질소 도핑과 촉매 활성에 미치는 영향을 확인하였다. 멜라민과 탄소의 혼합물 내 멜라민 함량을 각각 다르게 혼합 및 열처리를 하여 탄소 지지체에 질소를 도핑하였으며, 강한 정전기 흡착법으로 5 wt% Pd/NC 촉매를 제조하였다. 제조된 촉매 중, Pd/NC67 촉매는 96.1%의 1-페닐프로판올 전환율, 98.8%의 프로필벤젠 수율로 가장 활성이 높음을 확인하였다. 이는 탄소 지지체에 도핑된 질소의 양이 일정 범위까지 증가함에 따라 Pd의 분산도 및 입자 크기를 개선하고 염기점의 양이 반응 활성에 영향을 미쳐 나타난 결과임을 보여준다.

The propylbenzene (PB) produced through the hydrogenolysis of 1-phenylpropanol (PP) has the potential for significant market growth and commercial application. In this context, nitrogen-doped carbon (NC) has the capacity to alter the physical and chemical properties of a given substance, thereby rendering it a highly versatile catalyst support for hydrogenolysis reactions. In this study, we investigated the effect of the mass ratio of melamine on nitrogen doping and catalytic activity. The NC was obtained by modulating the mass ratio of melamine and calcination. Subsequently, the 5 wt% Pd/NC catalysts were fabricated using a strong electrostatic adsorption method. Among the catalysts, Pd/ NC67 exhibited the highest activity with a PP conversion rate of 96.1% and a PB yield of 98.8%. These results indicate that the incorporation of nitrogen into the carbon support, within a specific range, decreases, which subsequently influences the reaction activity. These results indicate that the incorporation of nitrogen into the carbon support within a certain range enhances the dispersion of Pd and reduces the particle size, and the amount of base point affects the reaction activity.
