Reliable renewable energy is a major sector with the constantly growing needs and dependency of energy almost everywhere today. Among various energy sources, hydrogen is most favorable due to its abundance, zero emission, storability, and high energy density. Hydrogen can be produced by water splitting where water is split into hydrogen (H2) and oxygen (O2) gases via hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Reliable and efficient ways to split water is by electrolysis and photolysis. The objective of this proposal is to synthesize two types of nanostructured materials - electrocatalysts and photocatalysts - for water splitting to obtain H2 gas by electrolysis and photolysis. Nanostructured 3d transition metal oxides (MO), hydroxides (MOH), sulphides (MS) and phosphides (MP) will be synthesized by electrodeposition, hydrothermal and anodization processes. Electrochemical baths with appropriate metal salts with controlled pH will be used to synthesize MO and MOH. MS and MP will be prepared by using hydrogen sulphide (H2S) gas and sodium hypophosphite in appropriate electrolytes. These electrocatalysts and photocatalysts will be used to fabricate electrodes for electrolysis and photolysis to generate H2 using HER. The outcome of this program will lead to in-depth comprehension of synthesis and characterization of nanostructured MO, MOH, MS, MP for H2 production by water splitting processes. HQPs, will be trained in this field of increasing demand in this fast advancing technological world. They will comprise graduate and undergraduate students, postdocs and research professionals, who will acquire comprehensive and hands-on training on material synthesis and characterization techniques, which is essential as the Canadian economy booster. Results will be published in peer-reviewed journals and conference proceedings, increasing Canada's visibility in energy research activities. New and intensive of existing Canadian and international collaborations will be established.

可靠的可再生能源是当今几乎所有地方对能源的需求和依赖不断增长的主要领域。在各种能源中，氢因其储量丰富、零排放、可储存、能量密度高而受到青睐。氢气可以通过水分解产生，其中水通过析氢反应（HER）和析氧反应（OER）分解成氢气（H2）和氧气（O2）。可靠且有效的分解水的方法是电解和光解。该提案的目的是合成两种类型的纳米结构材料——电催化剂和光催化剂——用于水分解，通过电解和光解获得氢气。纳米结构3d过渡金属氧化物（MO）、氢氧化物（MOH）、硫化物（MS）和磷化物（MP）将通过电沉积、水热和阳极氧化工艺合成。具有控制 pH 值的适当金属盐的电化学浴将用于合成 MO 和 MOH。 MS 和 MP 将通过在适当的电解质中使用硫化氢 (H2S) 气体和次磷酸钠来制备。这些电催化剂和光催化剂将用于制造用于电解和光解的电极，以利用HER产生H2。 该计划的成果将导致深入理解用于水分解过程生产氢气的纳米结构 MO、MOH、MS、MP 的合成和表征。总部人员将接受在这个快速发展的技术世界中需求不断增长的领域的培训。他们将包括研究生和本科生、博士后和研究专业人员，他们将获得材料合成和表征技术方面的全面实践培训，这对于加拿大经济的助推器至关重要。结果将发表在同行评审的期刊和会议记录中，提高加拿大在能源研究活动中的知名度。将建立新的、深入的现有加拿大和国际合作。
