Polarisation Photocatalysis

Tianyi Ma: The novel concept of Polarisation Photocatalysis was raised in this work. Compared with traditional strategies to enhance photocatalysis, such as constructing heterojunctions and atomic doping, it features a durable and permanent in-built electric field for directed charge separation, cost-efficiency without introducing external chemicals, energy, or field input, as well as an extendable concept involving not only crystal framework asymmetricity, but also crystal facet and nanostructure asymmetricity.

Tianyi Ma: The substantially lifted catalytic performance together with government and industry investments makes the scaling up of photocatalysis technology realistic. Namely, a photocatalytic solar-to-H₂ generator (Australia-based) was developed to produce 1kg of green hydrogen per hour, making it one of the world-first successful demonstrations to directly produce hydrogen from seawater at an extremely low cost.

Tianyi Ma: In the next few years, we will focus on developing more efficient and cost-effective photocatalytic materials and systems. This may involve optimising photocatalysts and reaction conditions, and developing new methods to promote photocatalytic performance. We are also looking to develop photocatalytic systems that can be integrated into existing technologies, such as solar panels or air purification systems.

Tianyi Ma: There are many factors to motivate our team, such as the desire to solve scientific problems, curiosity, and the pursuit of knowledge and innovation. In the case of the research on polarisation photocatalysis, our team was motivated by the potential for this technology to address pressing environmental and energy-related challenges.

Additionally, the opportunity to develop new materials and explore new areas of photocatalysis greatly inspires our team members.

Tianyi Ma: Successful academic research must require effective collaboration among a team or between different research groups or disciplines. Researchers with strong collaborative skills can facilitate teamwork, share ideas, resolve conflicts, and bridge gaps between different fields, leading to more successful research outcomes.

Tianyi Ma: Good research culture should be characterised by open communication, collaboration, and a commitment to ethical and transparent research. A positive research culture could encourage diversity, inclusivity, and the exchange of ideas across different backgrounds and perspectives. It can also provide resources and opportunities for professional development and recognise and reward excellence and contributions to the scientific community.

Tianyi Ma: Chemical sciences play a critical role in addressing many of the world's most pressing challenges, such as developing new medicines, producing sustainable energy sources, and reducing environmental pollution. Chemical scientists are working to develop new materials, technologies, and processes that can improve our lives and protect the planet. For example, advances in catalysis have enabled the production of cleaner and more sustainable fuels.

Tianyi Ma: I would suggest they develop a strong foundation in the fundamentals of chemistry, including principles of physical, organic, and analytical chemistry. Seek out opportunities to conduct research, either through internships, undergraduate research programs, or graduate school. Network with other scientists and attend conferences to stay up-to-date on the latest research and developments in the field. Finally, keep an open mind and be willing to explore different areas of chemistry, as there are many exciting and rewarding career paths available to those with a background in chemistry.
