“…The process involves the reduction of protons to form hydrogen gas. Electrocatalysts are often used to facilitate and accelerate the hydrogen evolution reaction and improve the efficiency of the cell [12]. As the HER is the creation of water utilizing a flow of electrons, if we were able to supply the hydrogen and oxygen needed from splitting water, it would be a renewable source.…”

Quantum dots (QDs), a type of nanoparticles, have displayed promising applications within many scientific fields. A QD is a nanoscale semiconductor particle with unique quantum mechanical properties. These tiny structures, typically ranging from 1 to 10 nanometers in diameter, exhibit distinct electronic and optical behaviors due to their size-dependent quantum confinement effects. Their applications improve upon quality, energy consumption, and efficiency in LEDs, batteries, catalysts, solar energy, and more. This review article goes over the fundamentals of nanochemistry as a whole, before proceeding into more in-depth procedures on synthesizing quantum dots and delving into various applications today. The key points of this article are to introduce scholars who are new to the field of quantum dots in the fundamentals of quantum chemistry before elaborating on the improvements quantum dots have brought to many fields. This article covers in-depth enough to grasp most concepts behind these applications, but as a whole, this field is still relatively new, in which case new applications and improvements of quantum dots can be found. In the future, quantum dots may become a key to advancing society, with possible applications in medicinal processes, more efficient energy storage, better energy generation, and quantum computing, in addition to what QDs already improved within those fields.

Energy demand, global warming, environmental impacts, sustainability, and energy sources are some of the concerns faced by humanity. Quantum‐dot‐sensitized solar cells (QDSSC) are an alternative solution to addressing some of these issues, in addition to reducing the costs of producing electrical energy. However, QDSSCs present stability problems and low efficiency, less than 16%. In light of this challenge, this review aims to present the main strategies adopted to reduce energy losses that occur in each component of the solar cell, with a focus on one key component: the counter electrode (CE). The CE plays a crucial role in collecting electrons and regenerating the electrolyte, thus impacting the lifespan and efficiency of QDSSCs. As such, this review discusses the main advancements in CEs based on key materials such as metal sulfides, carbonaceous materials, and composites. The efforts related to the synthesis and application of different counter electrodes for QDSSCs are explored.
