The energy crisis is becoming a serious threat all over the world due to the increase in industrial and domestic consumption. Therefore, it is important to establish affordable and eco-friendly solutions that can effectively address and manage this complex issue. In this regard, photocatalytic water splitting is emerging as an environmentally friendly approach for hydrogen production, signifying a green technological advancement. The goal of this research program is to use inexpensive and abundant alternative sources for hydrogen production through water splitting. To achieve this, we will derive biochar from sewage sludge and other readily available Canadian waste materials. In contrast to conventional methods, our approach involves a multi-step process. Firstly, we will transform the biochar into nanometer-sized particles through ball milling. Afterward, we will perform band gap engineering with metal oxides, followed by the application of a super-activation process. This super-activation method is relatively unexplored but is recognized for its eco-friendliness and its potential to enhance the catalytic properties of the material. These steps will result in the improvement of solar radiation absorption, a reduction in charge recombination, and an enhancement in the stability of the prepared catalyst. These factors are crucial for enhancing the efficiency of photocatalytic hydrogen production. This project represents a new avenue for creating biochar composites with metal oxide materials, expanding their potential applications in sustainable energy. By introducing a cost-effective and environmentally friendly material to address the energy crisis, we are not only addressing a pressing global issue but also pushing the boundaries of green technology, paving the way for a more sustainable future. This program aligns seamlessly with Canada's goal of achieving net-zero emissions by 2050 and contributes to a low-carbon future through renewable energy production. Achieving the proposed program goals will support Canada in meeting its aim of reaching net zero emissions. This program offers a truly unique opportunity for training highly qualified personnel (HQP). Through the U of R's Clean Energy Technologies Research Institute research infrastructure, they are given access to state of the art lab instrumentations, software computational capacity, and training opportunities. Two PhD, two MASc, and two undergraduate students will benefit greatly from this initiative's exceptional training opportunities in materials and process development, which will also help industries flourish. These opportunities will focus on fields that are in high demand on the current job market in Saskatchewan and Canada.
