摘要

氢能是实现“碳中和”目标的关键性清洁能源之一，因此开发高效低碳制氢工艺至关重要。甲醇蒸汽重整（MSR）是一种具有潜力的制氢技术，但实现贵金属基催化剂的高产氢效率和高CO

选择性仍存在巨大挑战。采用水热法合成了纳米棒CeO

（CeO

-R）和纳米立方体CeO

（CeO

-C）两种形貌的载体，并构建了负载型Pt/CeO

催化剂（Pt/CeO

-R、Pt/CeO

-C）催化MSR反应。结合HRTEM、XPS和Raman等表征手段，探究了CeO

形貌对催化剂催化性能的影响机制。结果表明，优先暴露(111)晶面的CeO

-R表面氧空位较多，产生了更多的Pt

-O

-Ce

界面位点（本征活性中心）。在反应温度为325 ℃、甲醇水混合物（

O):

(CH

OH) = 3:1）进料流量为0.02 mL/min以及空速为34800 mL/(g·h)下，Pt/CeO

-R的产氢速率达到490.35 mmol/(g·h)，CO

选择性为92.9%。相同条件下，Pt/CeO

-C上CO

选择性仅有63.0%。本研究可为新型高效MSR催化剂设计提供借鉴。

Abstract

Hydrogen energy is one of the key clean energy sources for achieving the “carbon neutrality” goal

so developing efficient and low-carbon hydrogen production processes is of vital importance. Methanol steam reforming (MSR) emerges as a promising technique for hydrogen production

yet challenges persist in achieving both high hydrogen yield and CO

selectivity over noble metal-based catalysts. Herein

CeO

supports with different morphologies of nanorods (CeO

-R) and nanocubes (CeO

-C) were prepared by hydrothermal method for constructing Pt/CeO

catalysts (Pt/CeO

-R

Pt/CeO

-C). Combined with comprehensive characterization techniques

including HRTEM

XPS

and Raman spectroscopy

the morphology-dependent catalytic behavior in MSR reactions was studied. The results show that CeO

-R with exposure of dominant (111) facet exhibits more surface oxygen vacancies

generating abundant Pt

-O

-Ce

interfacial active sites (intrinsic active site). Under the conditions of 325 ℃

a methanol-water mixture feed flow rate of 0.02 mL/min (

O):

(CH

OH) = 3:1)

and space velocity of 34800 mL/(g·h)

Pt/CeO

-R achieves a hydrogen production rate of 490.35 mmol/(g·h) with CO

selectivity of 92.9%. Under the same conditions

the CO

selectivity is only 63.0% by Pt/CeO

-C. This study can provide valuable insights for the design of new high-efficiency MSR catalysts.
