preparation equipment include centrifuges, freeze dryers, ovens and ball mills while catalyst

characterisation equipment including temperature-programmed reduction (TPR) and desorption

(TPD) set-ups, as well as in situ FTIR spectrometer.

Offline GC HPLC

Catalyst testing equipment consist of 2 sets of fixed-bed

reactors and several batch reactors while product analysis

equipment including 2 online gas chromatography (GC), an

offline GC and a high-performance liquid chromatography

New Equipment

In 2020, under the support of Green Energy Programme, our lab has access to an advanced

4-channel CO2 reactor to analyze the hydrogenation of CO2 into methanol and other key

chemicals. The reactor was roughly half a million USD and is one of the most advanced of

its kind. Exciting project to come with this new weapon!

The lab also added a new ball mill for studies into mechanochemical synthesis.

3. Research Outcomes

7

2020 has been a year with outstanding achievements. Continued advances in biomass conversion

and single-atom catalysis have been made. Exciting discoveries have also been achieved in new

research areas of CO2 conversion and renewable nitrogen-containing chemical synthesis. A number

of articles have been published in leading journals, such as PNAS, Chem. Soc. Rev, Nat. Commun.,

Angew. Chem. Int. Ed., etc.

• S. Ding et al. High-temperature Flame Spray Pyrolysis Induced Stabilization of Pt Single-Atom

Catalysts Applied Catalysis B: Environmental, 2020, 281, 119471 (special issue in memory of Prof.

Maria Flytzani-Stephanopoulos).

• M. Hueley. et al. Observing single-atom catalytic sites during reactions with electrospray ionization

mass spectrometry Angewandte Chemie International Edition, 2021, DOI: 10.1002/anie.202011632.

Single-Atom Catalysis

Following our report in 2016 using heteropoly acids as anchoring sites for single atom catalysts, we

systematically developed a series of heteropoly acids to stabilize Pt and Rh single atom catalysts to

quantitatively elaborate on the relationship between catalyst structure, stability and activity (JACS). In-situ

X-ray absorption spectroscopy was applied to identify the rate-determining steps and key intermediates in

CO oxidation over Rh single-atom catalysts (Nat. Commun.). This year, we developed electrospray

ionization mass spectrometry based technique to precisely understand the active site composition and its

dynamic changes in catalytic cycles (Angew. Chem. Int. Ed.) At the same time, we continued the further

develop electrostatic interactions strategy to prevent agglomeration of single atoms. Finally, we successfully

utilized flame spray method to prepare thermally more stable single-atom catalysts.

C1 Chemistry: CO2 Utilization

Singapore has identified global warming as a major threat to its national development. In 2019, National

University of Singapore provided S$8 million to initiate the NUS Flagship Green Energy Program. Our

research group is fortunate to play a key role in it, in-charge of developing new catalysts for effective

conversion of CO2 into fuels and chemicals. We studied the reaction mechanism of CO2 hydrogenation

into formic acid and explained the role of catalyst supports and metal active sites during the reaction.

Encouragingly, Dr. Sun Qiming’s research work published in Angew. Chem. Int. Ed. as a hot article.

Due to COVID-19 pandemic, we were not able to conduct experiments for about half a year. Utilizing

this time, we finished publication of a few reviews in the area of biomass conversion, including one on

lignin conversion (Chem. Soc. Rev.) and one on metal particle size effect on biomass conversion (Chem.

Soc. Rev.) In shell biorefinery, our collaboration with Prof. Zhou to convert waste shrimp shells to high

value L-Dopa has been finalized and published (PNAS). This work received wide recognition and was

reported in NUS main website as well as Strait Times. We also explored into waste plastic valorization!

Representative Publications:

In 2018, our research group reported chemical synthesis of amino acids from biomass resources (PNAS),

which has aroused widespread interest and follow-up research internationally. We made major

progresses along this line in 2020. Several important works are published, expanding the boundaries of

biorefinery. A summery in the topic is under revision in Account of Chemical Research.

Representative Publications:

Dynamic catalysis

In 2019, we noticed a new trend in catalysis research from steady state to dynamic state. Under

oscillating conditions, the catalyst may behave differently compared with under constant condition due

to various reasons. As a result, the overall catalytic performance may be enhanced. Following a

perspective article on the topic (Chem. Sci.), we bravely explored into the field representing the first

team outside US to focus on the topic.

Exciting progresses will be communicated soon.
