  text: <jats:p>The search for metal-free and visible light-responsive materials for
    photocatalytic applications has attracted the interest of not only academics but
    also the industry in the last decades. Since graphitic carbon nitride (g-C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>)
    was first reported as a metal-free photocatalyst, this has been widely investigated
    in different light-driven reactions. However, the high recombination rate, low
    electrical conductivity, and lack of photoresponse in most of the visible range
    have elicited the search for alternatives. In this regard, a broad family of carbon
    nitride (C<jats:sub>x</jats:sub>N<jats:sub>y</jats:sub>) materials was anticipated
    several decades ago. However, the attention of the researchers in these materials
    has just been awakened in the last years due to the recent success in the syntheses
    of some of these materials (i.e., C<jats:sub>3</jats:sub>N<jats:sub>3</jats:sub>,
    C<jats:sub>2</jats:sub>N, C<jats:sub>3</jats:sub>N, and C<jats:sub>3</jats:sub>N<jats:sub>5</jats:sub>,
    among others), together with theoretical simulations pointing at the excellent
    physico-chemical properties (i.e., crystalline structure and chemical morphology,
    electronic configuration and semiconducting nature, or high refractive index and
    hardness, among others) and optoelectronic applications of these materials. The
    performance of C<jats:sub>x</jats:sub>N<jats:sub>y</jats:sub>, beyond C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>,
    has been barely evaluated in real applications, including energy conversion, storage,
    and adsorption technologies, and further work must be carried out, especially
    experimentally, in order to confirm the high expectations raised by simulations
    and theoretical calculations. Herein, we have summarized the scarce literature
    related to recent results reporting the synthetic routes, structures, and performance
    of these materials as photocatalysts. Moreover, the challenges and perspectives
    at the forefront of this field using C<jats:sub>x</jats:sub>N<jats:sub>y</jats:sub>
    materials are disclosed. We aim to stimulate the research of this new generation
    of C<jats:sub>x</jats:sub>N<jats:sub>y</jats:sub>-based photocatalysts, beyond
    C<jats:sub>3</jats:sub>N<jats:sub>4</jats:sub>, with improved photocatalytic efficiencies
    by harnessing the striking structural, electronic, and optical properties of this
    new family of materials.</jats:p>
